IMPORTANT

READ THIS BEFORE USING YOUR NEW MICROLOG

The Microlog must be manually initialized when you first receive it.

¾ To verify that your Microlog has been initialized properly,here is a technique we suggest you use.

Before initializing, go to the Microlog’s Utilities/System Setupscreen and set Auto Range:On. Initialize as described below,then go back to the Utilities/System Setup screen. If you seeAuto Range: set to Off , you have successfully initialized.

¾ Warning - Initialization resets all Microlog settings totheir factory defaults, deletes all downloaded ROUTE infor-mation, and deletes any measurements stored in the Microlog.

To initialize the Microlog:

With the Microlog OFF, simultaneously hold down the Microlog’s9 and 6 keys.

While depressing the 9 and 6 keys, press and release the ON/OFFkey, continue holding down the 9 and 6 keys until the Microlog’sfirst screen fully displays.

The Microlog’s status line at the top of the main menu displayshould indicate 100% of free memory.

Who Uses the Microlog/PRISM System?

The CMVA60 Microlog/PRISM System is used by experi-enced machinery maintenance personnel who wish to col-lect and analyze vibration data from their rotatingmachinery, to help reduce costs and downtime.

What is the CMVA60 Microlog System?

A CMVA60 Microlog System (Figure I - 1) consists ofthree components:

• A CMVA60 Microlog data collector, • A host computer with PRISM2, PRISM4 for

Windows, or equivalent software, and

• A support module.

IntroductionWho Uses the Microlog/PRISM System?


The CMVA60 Microlog Data CollectorThe CMVA60 Microlog data collector is a lightweight,portable, data acquisition and storage terminal (Figure I - 2). It collects machinery vibration, temperature, andother condition monitoring measurements. Together withvisual observations, the CMVA60 Microlog allows for de-tailed machine condition analyses in a harsh industrial en-vironment.

IntroductionWhat is the CMVA60 Microlog System?


CMVA55-1.w mf

The Microlog performs all the tasks required for machin-ery predictive (condition) maintenance. It automaticallycollects both dynamic (vibration) and static (process) meas-urements from almost any source, it provides easy to useset up screens for quickly capturing data related to specificapplications like balancing, tracking filter, cyclic analysis,and current analysis, and it allows the user to configure upto 12 measurements for automatic data collection at onemeasurement point. Using the same sensor, the user needpress only one button to sequentially collect all pre-config-ured measurements.

Figure I - 2. Model CMVA60.



A variety of input devices may be used with your Microlog. Vibration measurements are collected with ahandheld probe, magnetically mounted probe, permanentlymounted sensors, or from an installed monitoring system.Temperature measurements are collected with a non-con-tact infrared sensor or with a contact probe.

Values read from other indicators may be entered into theMicrolog by pressing the appropriate numeric keys on theMicrolog keyboard. You can also enter your observationsby typing them in languages or as coded notes.

In addition to its function as a data collector, the Microloghas all the functions and performances of a powerful ana-lyzer to capture and display high resolution spectra for de-tailed analysis. A Fast Fourier Transform (FFT)frequency spectrum and a time domain waveform are avail-able for display on the LCD (Liquid Crystal Display)screen.

The Microlog automatically turns itself off after 5 minutesof inactivity to preserve battery life (in all functions exceptAnalyzer, Transfer, Battery/Temperature, and Re-ports).

PRISM Host SoftwarePRISM2 (DOS version) and PRISM4 for Windows are op-tional support software packages that work with the Microlog to help machinery maintenance personnel man-age machine condition data.

¾ In this manual, the term “PRISM hostsoftware” describes both PRISM versions(DOS and Windows).

PRISM host software automatically performs the tediousclerical work required in sorting and saving data.



Through detailed printed reports it alerts maintenance per-sonnel to alarm conditions (exceptions from normal).

PRISM host software helps machinery maintenance person-nel to understand the true condition of their rotating ma-chinery and to base maintenance decisions on the actualcondition of machines.

PRISM host software excels in presenting collected ma-chinery data in statistical and graphic plot format to obtainuseful analysis data (Figure I - 3).

Refer to the PRISM host software’s User Manual for op-erational details.

¾ The host computer has varying minimumconfigurations depending on whichPRISM host software is used. See yourPRISM host software’s User Manual fordetailed minimum configuration informa-tion.

Figure I - 3. A PRISM4 Spectrum Display.



The Support ModuleThe CMVA6112 Support Module (Figure I - 4) is capableof fast charging the NiMH (CMVA50230-1) battery pack.

suppmod2.pcx

There are 2 LEDs and a Deep Discharge button on theCMVA6112 Support Module. The Deep Discharge buttonis used for deep discharging the battery pack in the sup-port module’s pocket. Once deep discharging is complete,the support module automatically fast charges the batterypack.

The “Battery in Charger” LED indicates the chargingstatus of the battery pack on the support module, the “Bat-tery in Microlog ” LED displays the charging status of thebattery pack in the Microlog.

The LEDs indicate the battery pack’s 3 different chargingmodes:

Deep Discharging (Support Module battery only) -LED flashes slowly.

Fast Charge - LED is ON continuously.

Figure I - 4.The CMVA6112 Support Module.



Trickle Charge - LED flashes quickly.

¾ Reference Appendix A for a detailed de-scription of battery capacity, care, andtesting.

¾ The CMVA6112 is powered by an univer-sal AC/DC adapter. Use of a differentadapter to power the Support Moduleshould be consulted with the manufac-turer, or the Support Module may be dam-aged.

Microlog System Connections

The support module (Figure I - 4) supplied with each Mi-crolog system provides a convenient, compatible interfacebetween the Microlog and its host computer through RS-232 connectors. The support module also contains the bat-tery charger for the Microlog’s batteries.

IntroductionMicrolog System Connections


> To connect your Microlog system:• Using the supplied CMSS50080, CMSS50080-

CE cable, or CMSS250 (25 PIN to 9 PIN adapt-er supporting 9 PIN serial ports), connect yourhost computer to the support module betweenthe connection marked COMPUTER on thesupport module and one of the serial ports(COM1 or COM2) on the back of your com-puter (Figure I - 1).

• Using the supplied CMSS50077 cable, connectthe support module to the Microlog between theconnector marked MICROLOG on the supportmodule and the 25-pin D connector on the topsurface of the Microlog Collector.

• Plug the support module into an AC power sup-ply through the external transformer adapter sup-plied with the support module.

¾ Before using your Microlog, check tomake sure that the transformer adaptersupplied with your support module is cor-rect for your electric line supply.The Microlog uses the same 25-pin Dconnector for connection to its varioussensors and to its support module.Keep the connector attached to insure itremains clean while in an industrial envi-ronment.

What You Will Find On The Main Screen

The Microlog collector has a large, supertwist graphic liq-uid crystal display (LCD). Everything needed to identifyand assess a measurement (identification, description, en-gineering units, warning alarms, last value recorded, andcurrent value) appears on the graphic LCD screen.

IntroductionWhat You Will Find On The Main Screen


When you first turn on the Microlog collector, the mainmenu and title block are displayed (Figure I - 5).

03-2mlog.pcx

Version NumberThe title block, displayed to the right of the main menu onpower up, includes the firmware version number. Use thisnumber if you call customer support.

¾ If you call customer support, you willalso be asked for the Microlog’s serialnumber. It is located on back of the Mi-crolog case..

The Microlog screen contains three main areas: statusline, working area, and prompt area.

Figure I - 5.The CMVA60 Microlog Power Up Screen.



The Status LineThe one-line strip at the top of your Microlog screen iscalled the status line (Figure I - 6).

screen00.pcx

The status line displays the current date and time (if youpreviously set them correctly). The status line also con-stantly reports on the percent of free memory available.Other items of information appear from time to time in thestatus line. They are:

• Signal Overload Warning (OV)

• Low Battery Warning (BT)• Out of Limit Collector Temperature Warning

(TP)

• Shift Lock On up arrow indicator

When the BT (low battery charge) indicator appears, youhave approximately 20 minutes to complete immediatemeasurements before the Microlog shuts down to preserveyour data. At this point you can replace the main batteryor connect the Microlog to its support module charger.All data and instructions in the Microlog are fully pre-served for up to 3 minutes by an internal power sourcewhile you change the main battery.

The Signal Overload Warning (OV) displays to warn ofprobable inaccuracies when an incoming signal overloadsthe internal signal conditioning. Do not record data withthe OV indicator continuously on. Instead, range up bypressing the up arrow key until the OV warning disappears.

IntroductionThe Backlighting Key


CMVA55-1.w mf

¾ Backlighting requires considerable powerand could reduce the time between batterycharges by as much as one-half (typicallyone-fourth).

BNC Connectors

Three BNC connectors (INPUT, PHASE, and OUTPUT)are provided on the CMVA60 Microlog. These connectorsprovide cabling flexibility to external sensors or externalmonitoring/recording equipment.

When using the two input BNC connectors (INPUT andPHASE) it is important to note that the multi-pin connec-tor’s “Cable Identification” has been disabled to achievethe flexibility of accepting signals from different sensors;including accelerometers, velocity and displacement sen-sors, process inputs, etc. Therefore, when the INPUTBNC connector is activated, the CMVA60 Microlog pro-ceeds to take data when the measurement is started, eventhough there is no sensor or cable attached.

¾ Power is supplied to BNC connectorsonly when Connector:BNC and SensorPower:ICP are selected in the Utilities/System Setup option.

What Is Typical Machinery?

This Applications section describes standard Micrologmeasurement setups for measuring typical machinery.

We realize there is really no such thing as “ typical” ma-chinery. Machine construction, installation, and operationdiffer greatly from one plant to the next, and who’s to saywhat is considered “ typical” . However, there is a generalclass of machinery consisting of machines that are com-monly measured with the same Microlog measurement set-ups. We have classified this machinery group as “ typical”machinery.

Typical Machinery - Typical machinery is consid-ered to be rotating equipment; such as fans, pumps,compressors, motors, or generators operating atspeeds between 600 RPM and 10,000 RPM. All typi-cal machinery has the following components:

shafts couplingsbearings

The Microlog’s measurement setups are nearly identi-cal when measuring components on typical machin-ery (whether the machine is a pump, fan, etc.)Therefore, instead of repeatedly describing identicalMicrolog setups for various machines, we group ma-chines commonly measured with the same Micrologsetups, and describe the standard Microlog setups formeasuring this group of machinery.

¾ Certain applications do not fall into the“ typical” machinery group as they re-quire variations in the Microlog’s stand-ard measurement setups. Specificallyvery low speed and very high speed com-ponents (found in paper machines and

Standard Microlog Measurement SetupsWhat Is Typical Machinery?


high speed turbomachinery) and recipro-cating machinery require different Microlog measurement setups than typi-cal machinery.

These generalizations may contradict what you consider tobe typical and non-typical machinery classifications. Keepin mind, they are used for organizational purposes only.

What Are Standard Measurements?

Because vibration is considered by many as one of the bestindicators of machinery condition, vibration measurementsare classified as “standard” measurements. Of the fourcommon vibration measurements (acceleration, velocity,displacement, and enveloped acceleration), velocity meas-urements are typically used to detect low frequency rota-tional events (for example, imbalance, misalignment,looseness, shaft bow, etc.) on the majority of rotating ma-chinery.

¾ Historically, velocity measurements havebeen most popular when measuring vibra-tion, however, because of improvementsin accelerometer technology, accelerationmeasurements are becoming more preva-lent.

Velocity - Since velocity is commonly the most frequentlow frequency vibration measurement, the Microlog’sstandard velocity measurement’s setup is the core ofthis Applications section.

A Standard Velocity Measurement flow chart de-scribes Microlog menu selections that set up a stand-ard velocity measurement. This allows the new userto reference the flow chart to quickly and consistently

Standard Microlog Measurement SetupsWhat Are Standard Measurements?


set up the Microlog for standard velocity measure-ments.

Acceleration measurements are typically used to deter-mine higher frequency rotational problems (for exam-ple, high speed machinery operating above 10,000RPM, and rolling element bearing and gearbox prob-lems).

Enveloped Acceleration (ENV Acc) measurements am-plify low frequency events in high frequency, repeti-tive vibration signals and successfully detect andmeasure rolling element bearing and gearbox prob-lems in early failure stages.

Displacement measurements are commonly used to meas-ure the relative distance between two surfaces. Onlight rotors operating in heavy, stiff casings, most ofthe vibration force is dissipated between the shaft andthe bearing surface, never reaching the housing’s sur-face. In this case, eddy probes and displacementmeasurements are a must.

Standard acceleration, ENV Acc, and displacement meas-urement Microlog setups closely resemble the standard ve-locity measurement’s setup with only a few exceptions. Inthis Applications section, following the velocity measure-ment flow chart, Standard Acceleration, Enveloped Ac-celeration, and Displacement Measurement setupsections describe deviations from a velocity measurement’ssetup (flow chart) that change a velocity measurement intoan acceleration, ENV Acc, or displacement measurement.We find this to be more efficient than repeating the entireflow chart, noting only a few exceptions.

Velocity Measurement Assumptions and Deviations

AssumptionsIt should be understood that the Standard Velocity Meas-urement flow chart settings are selected with the followingassumptions:

• “Typical” machinery is being measured for de-tection/condition monitoring purposes, not foranalysis purposes.

• “Typical” machinery is being measured for loworder rotational problems (for example, imbal-ance, misalignment, looseness, soft foot, bentshaft, etc.)

• An industry standard 100 mV/g accelerometeris being used. For example: SKF’s CMSS787AAccelerometer.

• Machine speed is greater than 600 RPM.

• Data collection speed is not a major concern.

(operating between 10Hz and 3kHz)

Standard Microlog Measurement SetupsVelocity Measurement Assumptions and Deviations


¾ It should be noted that longer measure-ment times often provide more valuabledata.

DeviationsWhen setting up a Microlog measurement, certain optionsettings are determined by the component’s speed and thetype of sensor used, these are:

Type - The measurement Type: option (for example, Ac-celeration, Acc to Vel, Acc to Disp, Velocity, etc.) isdetermined by the measurement’s sensor type and thedesired measurement.

Maximum Freq - The measurement’s maximum fre-quency (Fmax) setting is determined by the measuredcomponent’s speed and the type of defect anticipated.A rule of thumb sets the velocity measurement’sMaximum Freq. to 5 or 6 times the measured com-ponent’s running speed. This allows you to analyzethe measurement’s resulting FFT spectrum up to the5th or 6th harmonic.

For example, when performing a “standard” velocitymeasurement on a non-geared coupling, set Maxi-mum Freq. to the coupling’s running speed multi-plied by a factor of 6.

¾ High speed machinery, gearboxes, androlling element bearings are best meas-ured with acceleration or ENV Acc meas-urements. Reference the StandardAcceleration and ENV Acc Measure-ment sections for help with determiningMaximum Frequency settings for thesecomponents.



Standard VelocityMeasurement


Overview

Since velocity best measures rotational speed events, thissection uses a flow chart to detail the Microlog’s setup fora standard velocity measurement. This allows the newuser to reference the flow chart to quickly and consistentlyset up the Microlog for standard velocity measurements.

¾ Many users supplement velocity measure-ments with acceleration measurements.This allows a wide-band view of defectfrequencies in addition to the velocitymeasurements’ view of rotational speedevents.

¾ IMPORTANT - Before setting up the Microlog for a standard velocity measure-ment, you may wish to clear the Mi-crolog, then set Microlog Utilitiesoptions. Procedural descriptions follow.

Overview

Acceleration measurements are typically used to deter-mine higher frequency rotational problems (for example,high speed machinery operating above 10,000 RPM, androlling element bearing and gearmesh problems).

The following information helps Microlog users set uptheir CMVA60 Microlog to perform acceleration measure-ments on typical machinery.

Standard Acceleration Measurement Setup

To set up the Microlog for a standard acceleration measure-ment, use the Standard Velocity Measurement flowchart’s settings, with these exceptions:

Type: AccelerationLines: 800Low Freq Cutoff: 2 HzStart Freq: 0Maximum Freq:

• For Couplings/Shafts - For measurements onnon-geared couplings and shafts, use the stand-ard velocity measurement’s rule of thumb for set-ting Maximum Frequency: (5 or 6 times therunning speed).

Standard Acceleration MeasurementOverview


• For Bearings - When performing accelerationmeasurements on bearings, the MaximumFrequency is determined by the component’sshaft speed. Use the following table to set Maxi-mum Freq:

Shaft Speed Maximum Freq:

< = 1200 RPM 1 kHz1200-2400 RPM 2 kHz2400-3600 RPM 5 kHz

> 3600 RPM 10 kHz

These settings produce FFT spectra that allowanalysis of bearing fault frequencies.

• For Gears - When performing accelerationmeasurements on gearboxes, the Maximum Fre-quency setting is typically set to 4X the calcu-lated gear frequency (determined by the numberof teeth multiplied by the shaft’s RPM) plus10%.

4 (# of teeth x shaft speed) + 10%

In the resulting FFT spectrum, this allows youto see up to the 3rd order harmonics, and side-bands of the 3rd order harmonics.

¾ If sidebands are of interest, use 1600 linesof FFT resolution.

StandardDisplacementMeasurement


Overview

Displacement measurements are commonly used to meas-ure the relative distance between two surfaces. On light ro-tors operating in heavy, stiff casings, most of the vibrationforce is dissipated between the shaft and the bearing sur-face, never reaching the housing’s surface. Journal bear-ings (also known as sleeve bearings) are often used inthese situations. These bearings are “ fluid film” type bear-ings (they have no rolling elements). In this case, eddyprobes and displacement measurements are a must.

¾ Because of their accurate low frequencyresponse, eddy probes provide the mostaccurate displacement measurements. Ve-locity sensors provide strong response inthe mid frequency range. Integration of avelocity sensor’s measurement to displace-ment often provides acceptable results. Because of their indirect relation to dis-placement and their poor low frequencysensitivity, double integration of an accel-eration measurement to displacement gen-erally provides poor results.

The following information helps Microlog users set uptheir Microlog to perform standard displacement measure-ments on typical machinery.

1The Route Menu

¾ In this Chapter, the word “SET” refers toSET hierarchy items in PRISM2 (DOS) da-tabases, and both SET and machine hierar-chy items in PRISM4 for Windowsdatabases.

The ROUTE Feature of the PRISM Host Software

The PRISM host software’s Route feature allows you tobuild measurement collection sequences (ROUTEs) to helpyou perform the most efficient data collection.

When you originally constructed your PRISM host data-base by the hierarchy method, you more than likely organ-ized the hierarchy by area, by machine type, or by somesimilar grouping. If you downloaded POINTs to the Microlog collector in hierarchy order, a person collectingdata would probably have to “skip around” in the ROUTE,or would have to retrace steps to get to the next data collec-tion POINT in the ROUTE. Even if you design your data-base using a “most efficient ROUTE” method, at the timeof data collection you may want to make changes to aROUTE list or to have a POINT appear in more than oneROUTE.

What is a ROUTE?A ROUTE is a list of POINTs arranged in sequence for themost efficient data collection.

The advantage of ROUTE data collection is that measure-ments can be sequenced for the most efficient data collec-tion regardless of their location in the hierarchy. Thismethod also allows a measurement POINT or POINTs to

The Route MenuCollecting Data


¾ Returning to the ROUTE list allows youto collect measurements elsewhere in thesequence, or to go back to the host com-puter and upload the data you have col-lected.

The Route List

In the Microlog’s ROUTE list, measurements transferredfrom the PRISM host software for collection in ROUTEmode may be stored by hierarchy or by ROUTE name.

An empty NONROUTE SET always appears at the top ofboth ROUTE and hierarchy lists (see Figure 1 - 1). AllNONROUTE and ANALYZER measurements are storedin the NONROUTE SET.

In both hierarchy and ROUTE lists, move the pointer barwith the up and down arrow keys to select a SET, aROUTE, or a specific measurement POINT for measure-ment. When measurements are collected in sequence, thepointer bar moves automatically to the next measurementin the list.

The open/close indicators (equals or hyphen symbols) ap-pear to the left of all subSETs in a hierarchy list. The equalsymbol (=) indicates that a SET is open, displaying subordi-nate SETs and/or POINTs. The minus symbol (-) indicatesthat the SET is closed, concealing all subordinate POINTS.

The leftmost column on the ROUTE list shown in Figure 1- 1 contains the letter N (no data), indicating nothing hasyet been recorded, the letter D (data), indicating a measure-ment has been recorded, or the letter M (messages), indicat-ing an instruction text screen.

Although a ROUTE list is somewhat simpler than a hierar-chy list, the Microlog is able to skip entire machines (ex-

Speed TaggingSpeed tagging allows for very accurate speed values for dy-namic Microlog measurements, even in variable speed ma-chinery.

Using PRISM4 software, you can quickly select multiplePOINTs (Microlog dynamic POINTs) from the hierarchylist (these POINTs are referred to as speed tagged POINTs)



to associate with (link to) a specific Microlog dynamic ormanual input speed reference POINT.

The speed reference POINT can be a tach POINT, dynamicdata POINT, or manually input speed value. Data collectedfor the speed tagged POINTs reflect the rotating speed oftheir associated speed reference POINT.

¾ For dynamic speed reference POINTs, useeither Order Track frequency type basedPOINTs with a tach, or use Fixed Span fre-quency type and use the Microlog’s SetSpeed (1XRPM) feature to determine thespeed value for the speed referencePOINT and its associated speed taggedPOINTs.

¾ IMPORTANT - The speed referencePOINT (Speed POINT Id) must be col-lected (by the Microlog) prior to collectingits speed tagged dynamic data POINTs.Set up your PRISM4 ROUTE or databasehierarchy to facilitate data collection ofspeed POINTs prior to data collection ofPOINTs associated with speed POINTs.

¾ The speed reference POINT cannot be in-cluded in an MPA group of POINTs, how-ever, dynamic data POINTs linked to thespeed reference POINT may be (see theMulti-POINT Automation section laterin this chapter).

Speed Ratio

The Microlog determines the actual running speed fora linked measurement by multiplying its associatedspeed reference POINT’s speed value by the speed



tagged measurement’s Speed Ratio (specified inPRISM4).

¾ IMPORTANT - The dynamic measure-ment’s Speed Ratio setting must begreater than 0. A 0 setting disables speedtagging. In this case, the measurement’sspeed value is established using the meas-urement’s Speed field setting (manuallyinput in the POINT Setup dialog).

Error Messages

If the linked speed reference POINT does not precedethe speed tagged dynamic data POINT in the Microlog’s ROUTE list, speed tagging is disabled andthe following message appears when attempting to col-lect data for the speed tagged dynamic data POINT:

WARNING!

Running Speed (RPM) point used for SpeedTagged Point (Point Id) has not been down-loaded.

ENTER - to collect data using point setup’s de-fault speed value.

ESC - to abort data collection.

• Press ENTER to collect data. The measure-ment’s speed value is calculated using the meas-urement’s Speed field setting (manually input inthe POINT Setup dialog) multiplied by the meas-urement’s Speed Ratio value. Again, speed tag-ging is disabled.

If the speed reference POINT has been downloaded tothe Microlog in the proper hierarchy position but nodata has been taken on it, the following message ap-



pears when attempting to collect data on its associatedspeed tagged dynamic POINTs:

ERROR!

Hints for Efficient Data Collection

Reducing KeystrokesAside from the Microlog’s Multi-Point Automation fea-ture described at the end of this chapter, there are otherways the Microlog collector can be set to minimize thenumber of keystrokes required during ROUTE collection.Setting Route Mode:Normal in 6:Route Setup in the8:Utilities main menu (see the Utilities chapter) requiresone keystroke to collect an FFT spectrum, a second key-stroke to exit the FFT display when spectrum averaging iscomplete, and a third keystroke to advance the collector tothe next POINT. When Route Mode:Auto is selected, en-tering a measurement advances the pointer bar to the nextmeasurement POINT without additional keystrokes.

The fastest (but perhaps not the best) way to collectROUTE data is to use the following settings in 8:Utili-ties/Route Setup, see Chapter 8, Utilities:

Route Mode:AutoRoute Spectrum:HideSensor Mode:Always OnRoute Collection:FastAuto Range:Off

The Route MenuHints for Efficient Data Collection


¾ Use AutoRange:Off only when full scalefor each POINT is set to a value largeenough that no overload conditions occur,otherwise AutoRange:On is recognized.

In both Route Spectrum:Hide and Route Spec-trum:Show, you may manually record an FFT spectrum,whether or not required by programming, by pressing theSAVE function key.

Auto RangeThe Microlog collector can be configured for manual(Auto Range:Off) or auto amplitude range (AutoRange:On). See the Utilities chapter for more detail. ForAuto Range:Off, the Microlog sets the amplitude range tothe value downloaded to the Microlog from the PRISMhost software’s database.

The Microlog will not allow dynamic data to be collectedduring overload state. The Microlog reports input signalstoo large for the display with an OVERLOAD SIGNALbanner on the screen, and with the overload indicator (OV)in the center of the status line (top line) of the display. If asignal overload is indicated, the full scale amplitude rangeshould be increased to prevent amplitude errors. Duringdata collection, the full scale amplitude range may be in-creased or decreased from the Dynamic Data Point or FFTdisplays with the up and down arrow keys.

Whether Auto Range:Off or Auto Range:On is set, theamplitude range may always be increased and decreasedmanually during data collection by pressing the up anddown arrow keys.

The Route MenuHints for Efficient Data Collection


The ProbeIf a magnetic or permanently mounted sensor is not used,it is important that you hold the probe steady and with evenpressure. The Microlog’s high speed acquisition requiresonly a few seconds to collect the averaged FFT spectrumthat experience has demonstrated is necessary for accuratetrending and analysis.

If the vibration probe loses contact or if you are forced todiscontinue collection averages for other reasons, such asan ambient temperature too hot to continue holding theprobe in place, the averaging process can be stopped at anytime by pressing <ENTER>. Recognizing this possibility,the Microlog divides by the number of averages actuallycollected rather than by the number specified. Thus, as anFFT spectrum is being averaged, the values stored and dis-played are accurate for the number of averages collected upto that point. If the averaging process has to be stopped af-ter three or four averages, the reduction in accuracy is usu-ally minimal.

To Make An On-the-Spot Analysis

You may do a preliminary analysis on collected FFT Spec-tra. A movable cursor, controlled by left and right arrowkeys, is provided to give you an accurate value of both am-plitude and frequency of individual spectral components onthe Microlog’s display.

Digital values of amplitude, frequency, and multiple of OR-DER of machine running speed at the cursor position aredisplayed in the lines directly above the spectrum.

If running speed was not set correctly in the host or is notthe actual running speed (for example, in a variable speedmachine), running speed may be set from the spectrum dis-play.

The Route MenuTo Make An On-the-Spot Analysis


> To set running speed from the spectrum display:

• Place the cursor on the component in the spec-trum identified as running speed.

• Press the 1XRPM key.

The order displayed above the spectrum changes to 1.0.The speed established is recorded with the spectrum andtransferred back to the host computer as a permanent re-cord of actual running speed at the time the spectrum wascollected. This ensures orders are correctly listed on anysubsequent printouts.

¾ FAM marker frequencies are also updatedusing the new running speed.

Several other valuable analyzer functions are initiated bypressing labeled keys in the function keypad. Applicablekeys and their functions are described in the Analyzerchapter.

Spectral Banding

Spectral Banding provides alert and danger alarms onboth peak and overall spectral values within a defined fre-quency band.

The Microlog has the capability to process and display upto 12 spectral bands that have been pre-defined and down-loaded from a PRISM host software database.

On the Microlog, defined spectral bands appear on the dis-played spectrum. Peak values and setpoints appear asdashed lines, while Overall values and setpoints appear assolid lines.

¾ In order to view spectral bands, the Microlog’s 8:Utilities menu Route Spec-trum option must be set to Show.

The Route MenuSpectral Banding


¾ The overall for each band is calculated us-ing the same detection method (RMS,Peak to Peak, or Peak) as specified for thePOINT’s overall.

An A or D is displayed above the Peak Level line or Over-all Level line when an alarm condition occurs.

• Press < ENTER> and the pointer bar ad-vances to the next field on the screen (AverageType).

Average Type - Press MENU to view the choices.

Off - Produces the same results as setting AverageType:Average and Number of Averages:1. TheFFT displays components scaled by the selectedmethod of detection and updates at its maximum, real-time rate.

Average - The summation of the magnitude of eachspectral line is divided by the total number of aver-ages (ensemble averaging). This is the most fre-quently used method of averaging for routine datacollection and analysis.

Pk Hold - Peak Hold holds the highest value receivedat each spectral line during the averaging time. Thismethod of averaging is very useful when the signalcontains a great deal of amplitude variation and theprimary objective of the analysis is to see the maxi-mum reached by each component.

¾ For time waveforms, Average Type:Aver-age and Average Type:Pk Hold are notrecommended. Use Average Type:SyncTime instead.



Sync(hronous) Time - Averaging in the time do-main. This method of averaging requires a referencetrigger. Components within the signal which are syn-chronous with the reference trigger are reinforced,while noise quickly averages out. Synchronous timedomain averaging produces the most improvement insignal to noise ratio, and is advantageous whenever itis deemed necessary to extract very low amplitude sig-nals or to minimize the “noise” produced by the vi-bration of other machines nearby. When this methodof averaging is selected, the spectrum produced anddisplayed is the FFT of the averaged synchronoustime domain samples.

¾ To display Sync(hronous) Time averag-ing set the Trigger Source to External.

• Select your choice for Average Type with thepointer bar and press < ENTER> . Thepointer bar advances to the next field on thescreen (Average Mode).

Average Mode - Select the type of FFT average comple-tion. Press MENU to view the choices.

Cont(inuous) - Averaging of the latest N samples,where N is the number of averages selected for thesample. Equivalent to exponential averaging wherethe latest spectrum ensemble replaces the oldest inthe averaged sum.

Finite - Averaging proceeds for N samples. The aver-aging process stops and the result is displayed. (Thisis the averaging mode in Route Spectrum:Show dur-ing Route data collection.)

Repeat - Averaging proceeds for N samples, where Nis the number of averages you chose for the sample.



The spectrum average is displayed after N samplesare taken. The display is updated after each finite av-erage.

• Select your choice for Average Mode with thepointer bar and press < ENTER> . Thepointer bar advances to the next field on thescreen (Average Overlap).

Average Overlap - Overlap processing is advantageouswhen the time required to gather a time record ismuch longer than the time needed to calculate anFFT spectrum. In the Microlog this occurs at fre-quencies below 1,000 Hz (60,000 CPM).

For lower frequencies, the amount of overlap can beincreased to reduce the time required to collect agiven number of averages. Recognize, however, thatthe greater the overlap, the more information sharedbetween averages. Press MENU to view the choices.

Max - Uses whatever data is in the time record at thetime. This can be existing data, new data, or a mix-ture depending on how long it takes to collect time re-cord data. Results in the shortest averaging time butmay lack statistical accuracy.

75% - Uses 75% of existing data and 25% of newdata to calculate new FFT.


None - Each spectrum ensemble is new data added tothe sum.

Overlap processing is used to obtain enough new en-semble data for an accurate average. If the maximumfrequency is low and the FFT process time is fast, theaverage sum would include a high percent of old data



with maximum overlap. Below 2 kHz, 50% overlapand six averages is a reasonable ROUTE setup.

• Select your choice for Average Overlap withthe pointer bar and press < ENTER> . Thepointer bar advances to the next field on thescreen (Window).

Window - The type of window used in the FFT process-ing. A window function must be applied to any peri-odic time record prior to performing an FFT tominimize leakage errors. The Hanning and Flat Topwindow functions attenuate to zero both the leadingand trailing edges of the time domain buffer (to pre-vent leakage error caused by discontinuities in thetime record). Press MENU to view the choices.

Hanning - A dynamic signal analyzer window func-tion that provides better frequency resolution thanFlat Top, but with reduced amplitude accuracy. Use-ful for machine vibration measurements, general pur-pose measurements, and measurements containingrandom noise.

Uniform - A dynamic signal analyzer window func-tion with uniform weighting across time. Useful formeasuring transients or mechanical response measure-ments and in tracking mode.

Flat Top - A dynamic signal analyzer window func-tion which provides the best amplitude accuracy formeasuring discrete frequency components. Usefulfor calibration or machine vibration measurements us-ing displacement probes in fluid-film bearings.

• Select your choice for Window with the pointerbar and press < ENTER> .



• Press < ESCAPE> to return to the Dynamicsetup selection menu.

Spectrum Setup/Measurement Type:Orders

Measurement Type:Orders - Sets the spectrum display’shorizontal axis in orders (multiples of running speed). Re-quires an external 1XRPM trigger that is phase referencedto the rotating shaft.

Magnitude and absolute phase relative to the shaft refer-ence are plotted against orders (multiples of runningspeed). The advantage of this mode is that running speedcan drastically change, but the vibration amplitude andphase components are always plotted in the same orderedposition. In this mode, a low pass filter tracks runningspeed with cutoff frequency set by the menu selection ofmaximum orders. This ordered data of phase and ampli-tude in conjunction with the PRISM host software allowsfor an ordered vector polar plot.

Collecting NonRoute Dynamic Data

Once all setup steps are completed, you may observe andrecord dynamic POINT data. On the Dynamic menu se-lect 1:Take Data.

¾ The alarm levels for alarm1 and alarm2 inNonRoute and Analyzer modes are set in-ternally by the Microlog to 40% and 70%of full scale.

The Microlog does not allow dynamic data to be collectedduring overload state. The Microlog reports input signalstoo large for the display with an OVERLOADED SIGNALbanner on the screen, and with the overload indicator(OV) in the center of the status line (top line) of the dis-play. If a signal overload is indicated, increase the fullscale amplitude range to prevent amplitude errors. Duringdata collection you may increase or decrease the full scaleamplitude range in the Dynamic Data Point or FFT dis-plays with the up and down arrow keys.

Depending on how you set Average Mode in SpectrumSetup, the FFT may continue to average beyond the cho-sen number of averages (Average Mode:Continuous), itmay stop averaging and freeze the display (AverageMode:Finite), or it may repeat the entire averaging proc-ess to the chosen number of averages (Average Mode:Re-peat).

With this flexibility, the Microlog may be used to view aninstantaneous time domain waveform or FFT in real time;

The NonRoute MenuCollecting NonRoute Dynamic Data


view an averaged spectrum as it is collected; collect, aver-age, and freeze a spectrum; or view a repeated spectrum.

The controllable cursor is moved right and left with theright and left arrow keys to display frequency, magnitude,phase, and order of any spectral component. Markers, de-fined on the Marker Setup menu, may be turned on andoff with the MKRS ON/OFF function key.

Using the Function Keys

The dedicated function keys are active and may be usedwhen desired. Each function key is listed below with a de-scription of its action. The name of each key is followedby a letter in parentheses. When a function key functionis activated, this letter displays to the right of center of thescreen’s status line (top line).

FREEZE ON/OFF (F) - Toggles the FFT between active(dynamic) and hold modes. FREEZE may be usedfor detailed analysis of a dynamic spectrum. Press-ing the FREEZE key a second time restarts the liveFFT. FREEZE is marked by the letter F above theFFT display.

MKRS ON/OFF (M) - Toggles the markers on and off.

Harmonic markers are used to rapidly locate integralorders in relation to their fundamental (1X).

Sideband markers allow you to determine modula-tion frequency about a vibration peak. Sidebandmarkers are useful, for example, in locating a dam-aged tooth in a gearbox.

Relative markers are useful in the time domain for re-lating time intervals between events.

The NonRoute MenuUsing the Function Keys


¾ The F2 function key is an important aidin using markers. When markers areOFF, it advances the cursor to the highestpeak in the vicinity of the cursor. Whenmarkers are ON, it advances the cursor tothe next marker. When MarkerType:Sideband is active, the F2 key ad-vances the cursor to the next sidebandmarker so amplitude and frequency read-ings relative to the reference frequencycan be read. When Marker Type:Rela-tive is active, pressing the F2 key returnsthe cursor to the reference frequency.

Marker Mode:Cursor LockWhen Marker Mode:Cursor Lock is active, the MarkerType functions are:

Marker Type:Harmonic - In this function, a seriesof small square (box) markers are displayed at eachintegral multiple of the cursor position: 2, 3, 4, etc.

> To use the Harmonic function:• Place the cursor at the frequency to be ana-

lyzed.

• Press the MKRS ON/OFF key to toggle thefunction ON.

• Press the right arrow and left arrow keys tomove the cursor.

¾ You can press the right arrow or left ar-row key several times before the cursormoves, but each time an arrow key ispressed some markers will move. Thisspecial use of the arrow keys, called mi-



cro-motion, enables you to exactly alignthe markers on the peaks.

SHIFT/right arrow or SHIFT/left arrow causes thecursor and its related markers to move right or left ina one FFT bin sequence. This saves you turningmarkers off, moving the cursor, and turning the mark-ers back on when you are checking more than one setof harmonics.

¾ SHIFT is locked ON when the symbol displays in the middle of the top line ofyour screen.

Marker Type:Sideband - This function helps yousee sidebands around a central frequency.

> To use the Sideband function:• Place the cursor at the frequency around which

sidebands are to be observed.

• Press MKRS ON/OFF to toggle the markerson.

• Press the right arrow or left arrow keys untilthe sideband array “boxes” are aligned on thepeaks observed in the display.

¾ The entire sideband array may be movedleft or right with the left arrow or rightarrow keys after pressing the SHIFT key.Toggle the SHIFT lock off if you want touse other keys in lower case.



Marker Type:Relative - This function helps youmeasure the distance between two peaks.

> To use the Relative function:• Place the cursor at the desired beginning point

for the measurement.

• Press the MKRS ON/OFF key to toggle themarkers ON.

• Press the right arrow or left arrow keys toplace the cursor at the desired end point for themeasurement.

The difference between the marker and cursor dis-plays numerically directly above the graphic display.

Marker Mode:Fixed FreqWhen Marker Mode:Fixed Freq is active, the MarkerType functions are:

Marker Type:Harmonic - The marker displays on the ref-erence frequency and on all integral harmonics. Thecursor is free to move to any other spectral compo-nent so amplitude and frequency can be read.

Marker Type:Sideband - The main marker appears at thefrequency you specified and five sideband markersare spaced at the sideband frequency you specified.The cursor is free to move to any spectral component.

Marker Type:Relative - The main marker appears at thereference frequency. The cursor is free to move toany other spectral component so relative amplitudeand frequency can be read.



DISPLY EXPAND (D) - This function graphically ex-pands the contents of a time or frequency domain dis-play vertically and/or horizontally to use the fulldynamic range of the Microlog. It reveals charac-teristics which may be hidden by the display mode orby the resolution without changing data collection pa-rameters. To activate the DISPLY EXPAND func-tion, press its key on the keypad. The actualexpansion is accomplished by arrow keys.

¾ In a split screen display, DISPLY EX-PAND is active on the screen occupied bythe cursor. SHIFT CURSOR and DIS-PLY EXPAND can be used to selectivelyexpand one of the two screens displayed.

SAVE

> To assign an ID to a dynamic data display and store thedata:

• Press the SAVE key, a 20-character window dis-plays.

• Enter the ID or IDs in the window. • When the IDs have been specified, press

< ENTER> to store the display.

ZOOM IN (Z): Zooms in on the FFT spectrum in the fre-quency domain (time domain displays are not affectedby ZOOM ) to provide more frequency resolution be-tween lines. The Microlog takes the frequency at thecursor position and progressively divides the fre-quency range by half each time you press the ZOOMIN key. The lines resolution across the zoomed fre-quency range remains approximately constant.



Example: Suppose the current frequency range isfrom 0 to 60000 CPM with 400 lines resolution andthe cursor is at 12000 CPM.

When you press ZOOM IN , the new frequency rangeis 30000 CPM with 400 lines resolution and the cur-sor will still be at 12000 CPM.

Press ZOOM IN again to produce a new frequencyrange of 15000 CPM with the cursor still at 12000CPM.

¾ Although the Microlog displays only aportion of the increased resolution spec-trum in ZOOM , the full frequency rangeis available at the same resolution in thesegment being displayed and can be exam-ined (panned) by moving the cursor be-yond the end of the visible frequencyrange with the left arrow or right arrowkeys. Panning moves the viewing windowto the right or left of the frequency range.

ZOOM OUT: Reverses ZOOM IN .

RESET MEASMT - Resets the FFT average to zero andrestarts the averaging. This is especially useful ifsomething happens during the FFT averaging processto invalidate the measurement, such as losing contactwith the probe. You may also reset when you wish torepeat a measurement for any reason.

1XRPM - Sets the frequency at the cursor position to themachine running speed, and uses the value as the in-dex for the order display.



> To use the 1XRPM function:• Move the spectrum cursor to the spectral compo-

nent (peak) you have identified as running fre-quency.

• Press the 1XRPM key. The order displayed ona line above the FFT reads 1.0 or close to 1.0.

As the cursor is moved across the spectrum, the or-der displayed indicates the order value relative to therunning frequency set with 1XRPM.

¾ The Microlog interpolates between adja-cent spectral lines to arrive at an accuratevalue of running frequency. Since ordersare calculated to the center of spectrallines, they may be displayed as 1.01,2.05, etc.

F1/F2 -

F1 - toggles between displaying the value at the cur-sor and displaying the overall value.

F2 -MKRS OFF - causes the cursor to jumpto the highest peak in the vicinity of thecursor.MKRS ON - causes the cursor to jump tothe next marker.

SHIFT CURSOR - When the dual screen option is cho-sen in the Trace field (in Display Setup), this keytoggles the cursor between the two screens.

¾ In a dual screen display, Function Keysact on the screen with the cursor.



LIN/LOG (L) - Toggles the spectrum display between lin-ear and logarithmic amplitude scales. LOG enablesviewing very low level spectral components on thedisplay. The normal or default condition is set toLIN.

¾ In Log mode, the amplitude of the cursordisplayed above the graph reads in linearamplitude (such as Gs or IPS) althoughthe vertical axis of the graph is scaled indB.

PGUP - During data collection, press PGUP to doublethe maximum frequency.

PGDN - During data collection, press PGDN to cut themaximum frequency in half.

Basic Balancing Tips

• The basic balancing setup limits the user to fourbasic balancing configuration settings. This lim-ited choice selection focuses on the basics and isdesigned to prevent the beginning user from be-ing confused or intimidated by menu selections.

• After running a trial run using a trial weight,the CMVA60 automatically checks to see if the30-30 rule was passed. If it did not pass, theuser has the option of re-trying the trial runwith a different trial weight/angle, exiting, orcontinuing to the trim run operation. (30-30 rule- trial weights applied to an estimated balanceplane position must produce at least a 30%change in amplitude or 30o change in phasefrom the initial data.)

The Applications MenuBasic Balancing Tips


• More than one trim run can be executed to fur-ther "fine-tune" the trim adjustment. Word ofcaution: there is a limit as to how fine a tuningcan be conducted. There will be a point whereany further trim weights added will not improvethe balancing or can actually make it worse.

• After completing a balancing job and returningto the Balancing(Basic) menu, the job shouldbe saved. By saving a job, it can be retrieved ata later time for re-balancing or reporting.

• If the CMVA60 powers down in the middle of abalancing job, perform the following sequenceto return to where you left off:

1. Power up the unit.

2. Select Balancing (Basic).

3. Select Select Balance Job.

4. When prompted with "A previous job hasbeen detected in RAM" message, press <EN-TER> to return to the state you had left off.

Balancing (Advanced)

OverviewFollowing is an overview of steps performed in a “ typical”balancing procedure.

The Applications MenuBalancing (Advanced)


¾ If rotor length to diameter ratio is lessthan .5 (L/D < .5), then single plane bal-ancing will probably reduce imbalance toacceptable levels. Overhung rotors arealso a special case in which single planemethods are used.

Refer to the Additional Balancing Notes section at theend of this Balancing (Advanced) section for a more de-tailed discussion of setup procedures and application guide-lines.

Single Plane BalancingThe balancing procedure in general is as follows:

Trigger

Machine balancing requires a shaft 1X signal eitherto the external trigger BNC input or to the phaseadapter connector. The trigger signal is normally ob-

tained from the ± TTL output of one of three triggers:

• converters• light sensitive or laser beam• reflective systems or the SKF StrobeLite

Balance Setup

Setup menu entries control all measurement parame-ters required for the balancing sequence. There is noneed to escape from this menu to any other menu toperform the measurement sequence setup.

Reference Run

At this point, the machine’s “ initial” measurement isstored.

The Tracking screen displays the running speed,which must be stable within 1 CPM to ensure goodphase data.



Trial Run/Trial Weight Estimate and Setup

The Trial Weight Estimate is based on the criteriathat the trial run centrifugal force does not exceed10% of the bearing shaft load. Trial weights are ap-plied to an estimated balance plane position and mustproduce at least a 30% change in amplitude or 30o

change in phase (30-30 rule) from the initial data.

Trial Run/Trial Weight/Trial Run 1

After trial weights have been installed, the machine isrun up to the same stable speed as with the initialreadings. Stable speeds are very important.

A warning displays if the 30-30 rule described aboveis not met.

Trial Run/Correction Weights

After both the initial and trial runs are completed, in-fluence coefficients are calculated, and are used to de-termine the Initial Correction Weight locations.

Trial Run/Correction Weights/Split Options

Often, either the correction weight must be split toconform to the balance weight hole pattern or otherweights in the balance holes must be combined.These options are available in the Utility Functionsmenu.

Trim Run/Trim Run

Once the trial weights have been removed (WeightsLeft in Forever:No) and the initial weight installed,trim run data is collected and stored.

Trim Run/Calculate Trim Weight

Influence coefficients that were calculated for the in-itial correction weight are used again to obtain thetrim weight.



Save Balance Job

If desired, the current balancing job may be saved topermanent memory for later retrieval.

Report

A hard copy report of the balance data/Influence Co-efficients is produced when the printer adapter inter-faces the Microlog with either a laserjet or dot matrixprinter.

Two Plane BalancingIn two plane balancing, the measurement sequenceproceeds in the same order as single plane balancing,except two trial weights and two trial runs are re-quired to calculate the four influence coefficients(only 1 coefficient exists for single plane). Since theCMVA60 is a single channel instrument, the bearingmeasurements of plane A and B are performed sepa-rately.

Advanced Balancing Tips

• When conducting identical balancing jobs, loada previously saved, identical job, then go to Bal-ance Setup and change the balance setup "ID:".When saved, is saved as a separate balancingjob under the new ID.

• Prior to balancing, ensure that the CMVA60date/time is set correctly. This data is saved

The Applications MenuClearing the Current Job From Temporary Memory (RAM)


with each job, and can be retrieved and dis-played/printed at a later time with the job.

• If the Operator ID option is enabled and down-loaded from PRISM (v1.30 or later), enablingthe operator ID option in the CMVA60(Main/Utilities/Route Setup/Operator ID Tag-ging) tags each balancing job with the operatorID. When enabled, the ID can be displayed byselecting Balancing (Advanced)/Review/EnterData/View Data, and printed on reports.

Balance Setup

In the Balance Setup, normal analyzer input optionsare available, such as Type, Full Scale, Detection,and Sensitivity.

The Microlog is set to the tracking mode, which de-faults to Order analysis, 100 lines of resolution, Ex-ternal trigger, External trigger source, Uniformwindow and 10 orders for normal bandwidth. Ifwide or narrow bandwidth is selected, then 20X or10X orders is set up. These orders essentially reflectas 20%, 10%, or 5% bandwidth about the 1X FFTcomponent. The narrow bandwidth is useful for en-hancing the signal to noise ratio, when the trim runsignals are imbedded in noise.

Average Type

Should be set to Average:Off or Average:SyncTime. If phase readings vary, even though the run-ning speed is stable within tenths of CPM, then Aver-age:Average or Average:Sync Time should beselected.

¾ Sync Time averaging is most advanta-geous when nearby machines are runningat nearly the same speed, and producing

The Applications MenuAdvanced Balancing Tips


crosstalk. These non-coherent crosstalkcomponents tend to a zero average usingsynchronous time averaging.

Shaft Trigger

The trigger input to the CMVA60 can be appliedeither to the Microlog’s BNC trigger input, or thephase adapter/multi-pin connector. The phase adapt-er is used with the light sensing, laser beam, or SKFStrobeLite systems. The outputs from these devicesare TTL levels.

SKF StrobeLite

This unit connects to the phase adapter with a cablethat takes the accelerometer signal for lock and trackoperation, sending back a TTL trigger signal to theMicrolog digital interrupt controls.

The StrobeLite is functionally set up by these sequen-tial steps:

• The StrobeLite is adjusted by the internal gener-ator until the flash is synchronized to reflect a1X stopped view of the reference shaft marking.

• When the shaft reflective reference is a stableview, the strobe control is switched to the track-ing position. At this time, it is important thatthe internal control knob remain in a locked po-sition without change. The knob not only con-trols the internal generator, but also controls abandpass filter to enhance the 1X accelerometercomponent.

• When the accelerometer tracks and locks theflash to a 1X synchronous display, the phase ad-justment is positioned such that the shaft markcoincides to a reference point on the bearingpedestal. This spatial reference point is used forall measurement runs; Initial , Trial , and Trim .



• Only when phase adjustment positions the flash-ing shaft marking to this spatial reference pointare the Take Data measurements valid.

• The StrobeLite’s slope must always be positivesince it is the positive slope that shifts with thephase adjustment.

Trim Run

The trim run is performed after the data from the In-itial Run and the Trial Run s are entered into the cal-culations for the Influence Coefficients. Once thesecoefficients have been computed, they can be used infuture balancing of these specific machines by manualentry in the Review/Enter Influence Coefficient win-dow.

¾ If the coefficients are manually entered,then all Take Data measurements thereaf-ter are trim runs.

Combine and Split Weights

These functions are useful when several weights mustbe positioned to prescribed balance points to beequivalent to the needed correction weight (SplitWght), or when several weights must be combined tobe equivalent to the specified correction weights.The Combined Weight function is also useful for cal-culating the sum or difference of Take Data measure-ments. It is well known that the vector sum of thetwo bearing measurements in two plane is static im-balance, while the difference is twice the couple im-balance.

The Combined Weight function computes twice thecouple by adding 180o to one measurement entry (dif-ference). It is only necessary to enter the two vectorsMag/Phase for the static (sum).



Runout or Slow Roll Vectors

The Eddy Probe transducer is used when PointType:Displacement is selected. A Runout field ap-pears in the Setup screen which modifies the meas-urement of each Take Data run. Eddy currenttransducers measure the shaft surface variations aswell as the high spot dynamics. The shaft surface im-perfections often add to this dynamic signal as distor-tions that affect measurement accuracy, especiallyduring balancing. The slow roll or runout vector cor-rection is performed at low speeds where imbalanceforces are negligible and the surface imperfectionsare the motor component contributions. Once theshaft is measured for runout, this data is vectoriallysubtracted from each data collection run.

Tracking Filter

The Tracking Filter application can be used as a balanc-ing tool. It produces a tabular display of magnitude andphase of the shaft vibration high spot relative to an abso-lute shaft reference.

A condition ratio criteria has been empirically determinedfor Envelope Current measurements. It has been sug-gested that the rotor bar failure alert alarm be based on thecondition ratio exceeding 25%. That is, if the pole passpeak level is greater than 25% of the overall RMS level,then there is probable cause for concern of rotor degrada-tion.

Bump Test

A bump test (also called a hammer test) determines thenatural frequencies of a machine or a structure. The ideabehind the test is that when an object is impacted or“bumped,” the object’s natural or resonant frequencies areexcited. If a spectrum is taken while the object is vibrat-ing due to the impact, spectral peaks result, pinpointingthe object’s natural frequencies. A Microlog analyzer canbe used to capture this vibration response and to display aspectrum showing the resonant or natural frequencies.

Why Do a Bump Test?Vibration forces transmitted by rotating machines often ex-cite natural resonances in attached structures. Wheneversuch structural resonances appear, vibration responses areamplified and can result in fatigue failures. Structuralresonances can also mask the cause of a machine’s vibra-tion making it difficult to implement corrective machinemaintenance. Bump tests identify a structure’s resonantmodes and provide a maintenance engineer the opportunityto change the resonance frequency so as to reduce or elimi-nate damaging vibration.

The Analyzer Function

Small size, light weight, and large graphic display com-bine to make the CMVA60 Microlog collector a powerful,exceptionally versatile analyzer capable of viewing thespectral content of complex dynamic vibration signals aswell as their time domain waveform. The Analyzer func-tion is intended for field troubleshooting and searching forspecific dynamic characteristics and frequency compo-nents on complex machinery, such as bladed turbines andcompressors.

Spectra can be stored from the Analyzer function for latertransfer into the host data base.

When in the Analyzer display, commonly used functionssuch as Freeze, Save, Markers On, and Zoom are actu-ated using function keys on the keypad.

Setup

To simplify the setup procedure, two Analyzer user modesare available, Analysis and Normal. These modes are se-lected from the System Setup menu in the 8:Utilities func-tion (see the Utilities chapter).

User Mode: Analysis provides access to all Analyzerfunctions.


User Mode: Normal simplifies Analyzer operationby hiding option values for a number of options usedprimarily for highly specialized analyses.

Collecting Dynamic Data

When you have completed the Analyzer setup, select theAnalyzer menu’s 1:Take Data option.

¾ Alarm levels for alarm 1 and alarm 2 inNonRoute and Analyzer modes are set in-ternally by the Microlog to 40% and 70%of full scale.

The Microlog does not allow dynamic data to be collectedduring overload state. It reports input signals too large forthe display with an OVERLOADED SIGNAL banner onthe screen, and with the overload indicator (OV) in the cen-ter of the status line (top line) of the display. If a signaloverload is indicated, increase the full scale amplituderange. As described in the NonRoute chapter, during datacollection the full scale amplitude range may be increasedor decreased from the Analyzer display by using the upand down arrow keys.

Depending on how you set Average Mode in SpectrumSetup, the FFT may continue to average beyond the cho-sen number of averages (Average Mode:Continuous), itmay stop averaging and freeze the display (AverageMode:Finite), or it may repeat the entire averaging proc-ess to the chosen number of averages (Average Mode:Re-peat).

With this flexibility the Microlog collector may be used toview an instantaneous time domain waveform or FFT in

• When the IDs have been specified, press < ENTER> to store the display.

ZOOM IN (Z): Zooms in on the FFT spectrum in the fre-quency domain (time domain displays are not affectedby ZOOM ) to provide more frequency resolution be-tween lines. The Microlog takes the frequency at thecursor position and progressively divides the fre-quency range by half each time you press the ZOOMIN key. The lines resolution across the zoomed fre-quency range remains approximately constant.

Example: Suppose the current frequency range isfrom 0 to 60000 CPM with 400 lines resolution andthe cursor is at 12000 CPM.

When you press ZOOM IN , the new frequency rangeis 30000 CPM with 400 lines resolution and the cur-sor will still be at 12000 CPM.

Press ZOOM IN again to produce a new frequencyrange of 15000 CPM with the cursor still at 12000CPM.

¾ Although the Microlog displays only aportion of the increased resolution spec-trum in ZOOM , the full frequency rangeis available at the same resolution in thesegment being displayed and can be exam-ined (panned) by moving the cursor be-yond the end of the visible frequencyrange with the left arrow or right arrowkeys. Panning moves the viewing windowto the right or left of the frequency range.

Initialize

Initialize deletes all ROUTEs, ROUTE POINTs, and Non-Route POINTs stored within the Microlog. There are threeinitialization modes:

Mode 1 - When PROMs are changed, a two-key initializa-tion must be performed before using the Micrologagain. The two-key initialization is accomplished bysimultaneously holding down both numeral keys 9and 6 while turning the Microlog on. This process(called Format) erases all stored data and initializesthe Microlog’s menus, setup screens, and parametersto factory default settings.

¾ To verify that your Microlog has been in-itialized properly, here is a technique wesuggest you use.

Before initializing, go to the 8:Utili-ties/5:System Setup screen and set AutoRange:On. Initialize as described abovethen go back to the 8:Utilities/5:SystemSetup screen. If you see AutoRange:Off, you have successfully initial-ized.

Mode 2 - The Microlog may also be initialized from theUtilities menu. This method of initialization erasesdata, but does not affect existing screen setups.• At the Utilities menu, press 8 or move the

pointer bar to 8:Initialize and press < ENTER> . A PASSWORD pop-up windowappears (Figure 8 - 12).

Changing Batteries

The main battery pack in the Microlog collector can bechanged at any time without the loss of data, however, us-ers are advised to change batteries following upload orprint-out whenever possible to avoid any problems due to alow or discharged battery.

A low or failed back-up power source will be observed asa loss in the date or time and sometimes the substitution ofcharacters for numerals following a main battery change.When these symptoms are observed, data and instructionsin memory are likely scrambled or lost.

After a battery change, the date and time should always beobserved for symptoms of a low or failed back-up powersource. If a low or discharged back-up power source issuspected, reset the Microlog.

> To reset the Microlog:• Hold down the Microlog’s 9 and 6 key.• While depressing the 9 and 6 keys, turn the

Microlog on.

¾ Resetting the Microlog deletes allPOINTs.

Consult your local Service Center for repairing the back-up power.

CMVA60 Microlog A - 1User Manual

Battery Life

¾ Battery life is strongly influenced by a va-riety of factors (for example, temperature,battery age, sensor type, backlight us-age,etc.).

¾ SKF Condition Monitoring tests onCMVA60 units in the ROUTE mode haverecorded battery life in excess of 8 hoursfor NiMH batteries. These tests were per-formed with Sensor Power:Normal,which is the default and suggested methodof data collection for the CMVA60.

Battery Charging

The CMVA6112 Support Module is designed for use withNiMH (Nickel/Metal Hydride) Battery Packs(CMVA50230-1). We recommend the following proce-dures to obtain the most battery life from your battery.

The CMVA6112 Support Module is capable of chargingtwo battery packs simultaneously, one in the Support Mod-ule, and one in the Microlog connected to the SupportModule. To this purpose, the 6112 Support Module fea-tures two LEDs:

Battery in Charger LED - Indicates the status of the Bat-tery Pack in the 6112 Support Module.

Battery in Microlog LED - Indicates the status of the Bat-tery Pack in the Microlog connected to the 6112 Sup-port Module.

Battery Capacity, Care, and TestingBattery Life

A - 2 CMVA60 MicrologUser Manual

¾ Deep discharging only occurs in the Sup-port Module. The Microlog cannot deepdischarge its Battery Pack (through thesupport module).

Upon receiving your new NiMH Battery Pack, you shoulddeep discharge and fully re-charge your Battery Pack aminimum of three times to “ teach” your NiMH BatteryPack its full charge potential. After deep discharging andre-charging three times, the NiMH Battery Pack obtainsits maximum battery life and no longer requires deep dis-charging prior to re-charging (as NiMH batteries do not de-velop a “memory").

> To deep discharge, then fully re-charge your NiMH Bat-tery Pack:

• Place the NiMH Battery Pack in the powered on6112 Support Module.

¾ It may take 1-2 minutes for the LED tolight, depending on the battery’s residualcharge. If the LED does not light within5 minutes, the Battery Pack is defective.

• Press the 6112 Support Module’s black DeepDischarge button. The 6112 Battery in ChargerLED begins a “slow flash” (1 flash per second)as the NiMH battery deep discharges.

• When deep discharging is complete, the Batteryin Charger LED stops flashing and assumes a“constant on” status (the LED remains lit with-out flashing). This indicates that the BatteryPack is fast-charging.

• As the battery nears its full charge capacity, theLED changes from a “constant on” status to a“ fast flash” . This indicates the Battery Pack istrickle charging.

Battery Capacity, Care, and TestingBattery Charging


If necessary, you may remove the battery when the LEDchanges from a “constant on” to a “ fast flash” . However,to ensure the battery is charged to its full charge potential,you should leave the Battery Pack on a trickle charge for atleast two hours before removing the Battery Pack from the6112 Support Module.

• Perform the deep discharging/re-charging proce-dure described for the NiMH Battery Pack threeconsecutive times.

> To re-charge your NiMH Battery Pack (after 3 deep dis-charge/re-charges):

• Place the NiMH Battery Pack in the powered on6112 Support Module or in a Microlog attachedto the powered on Support Module. The appro-priate LED changes to a “constant on” status in-dicating the Battery Pack is fast charging.

¾ It may take 1-2 minutes for the LED tolight, depending on the battery’s residualcharge. If the LED does not light within5 minutes, the Battery Pack is defective.

¾ If the Battery Pack has a high residualcharge, the appropriate LED may go di-rectly to a “ fast flash” and skip the “con-stant on” status. In this case, the 6112Support Module has determined that theBattery Pack only requires a tricklecharge to bring it to full charge capacity.Allow the Battery Pack to trickle chargefor at least two hours before removing itfrom the Support Module.

Battery Capacity, Care, and TestingBattery Charging


• As the battery nears its full charge capacity, theLED changes from a “constant on” status to a“ fast flash” . This indicates the Battery Pack istrickle charging.

• If necessary, you may remove the battery whenthe LED changes from a “constant on” to a“ fast flash” . However, to ensure the battery ischarged to its full charge potential, you shouldleave the Battery Pack on a trickle charge for atleast two hours before removing the BatteryPack from the 6112 Support Module.

Unintentional Discharge

The 6112 Support Module immediately proceeds to dis-charge its Battery Pack when power is removed from the6112. To avoid this inadvertent discharge, remove the Bat-tery Pack from the Support Module before removingpower from the Support Module.

Aborting Deep Discharge

> To abort a deep discharge:• Remove the Battery Pack from the 6112 Support

Module, then reinsert the Battery Pack in theSupport Module, or

• Remove power from the 6112 Support Module,then re-apply power to the Support Module.

Thermal Switch - NiMH Battery Pack

The NiMH Battery Pack (CMVA50230-1) is equippedwith a Thermal Switch that disables the battery pack attemperatures exceeding 120o Fahrenheit (49o Celsius).

• Do not operate the Microlog in temperatures ex-ceeding 120o F (49o C).

• Do not store the Microlog in temperatures ex-ceeding 120o F (49o C).

• Do not charge the Microlog in temperatures ex-ceeding 110o F (43o C) (charging increases theBattery Pack’s internal temperature by approxi-mately 10o F).

> If the Battery Pack Thermal Switch opens as a resultof excessive temperature:

• Place the Microlog and Battery Pack in a coolerenvironment, and wait for the Battery Pack’s in-ternal temperature to cool.

• Once cooled, insert the Battery Pack in the Mi-crolog (if necessary) and power on. If the Mi-crolog powers up normally, the Battery Packswitch has closed and the Battery Pack/Mi-crolog are ready for use.

Appendix CWhy Zoom?

FFT frequency zoom narrows the analysis display intervaland increases frequency resolution. If there are closelyspaced peaks in a spectrum, increasing the number of FFTlines by depressing the front panel zoom key allows you toseparate the peaks, thereby achieving both amplitude accu-racy and improved frequency definition. Each ZOOM INkey press doubles the line resolution and halves the displayinterval. The resolution can only be increased to the 6400line limit of the single-channel Microlog and to 3200 linesin the two-channel Microlog. ZOOM OUT doubles thedisplay interval and halves the line resolution.

The Microlog uses a nondestructive method of applyingzoom. After the signals have been averaged and displayedwithin the restricted frequency interval, the spectral com-ponents outside the zoom display can be viewed by movingthe cursor to the display edge. Other spectrum sectors aredisplayed without performing new measurements.

The Microlog automatically sets the appropriate zoomrange whenever the fstart to fmax range is entered as lessthan 1/2 of the maximum frequency.

For example, if;

fstart = 500 Hz, fmax = 1 kHz, and Lines of resolu-tion = 400,

in order to provide the required 400-line resolution be-tween fstart and fmax, the Microlog automatically selects800 lines as the fzero to fmax resolution.

CMVA60 Microlog C - 1User Manual

If;

fstart = 750 Hz, fmax = 1000, and Lines = 400,

the Microlog automatically selects 1600 lines. Underthese circumstances, the display cannot be changed toview spectral components outside the fstart to fmax displayrange.

Zoom is often required to separate sideband peaks about amajor peak. The sideband frequency difference allowsyou to identify the modulation shaft frequency associatedwith the vibration peak.

Another application of zoom is to increase the time do-main display so repetitive transients can be viewed in thetime display. The time display for Lines = 400 and fmax

= 1 kHz is 0.4 sec. Increasing the resolution to 6400lines changes the time display range to 4.8 seconds.

To access the Remote Login screen:• From the main menu screen, select Transfer

with the pointer bar and press <ENTER> .

Logging in with the proper password allows a Microlog operatorto download and upload data by modem to an unattended hostcomputer’s database, allows the operator to change the databasebeing accessed, and allows the operator to clear the Micrologmemory in preparation for loading new ROUTEs.

Warning:

The Microlog protects from unintentionally deleting collecteddata. If an operator enters a different password than the personwho last used the Microlog, a "database conflict" displays and en-try is denied. The operator must intentionally initialize the Mi-crolog (erase all previously stored data) before attempting login.

Troubleshooting Modem Communications

PRISM4 Remote fails to communicate with the mo-dem. When in Auto Answer mode, PRISM4 Remotedisplays the “Modem NOT working or NOT on” mes-sage in the Modem Status window.

• Turn the modem off and power it on again.• Check the modem phone line and the serial ca-

ble (if the modem is external) to ensure a goodconnection.

• Verify the modem is connected to the rightCOM port (COM1 or COM2) and the correctCOM port setting is selected in the PRISM4sCommunication Preferences dialog box.

• Verify the modems COM port is not being usedby another serial device installed in your com-puter. Do not use the same COM port for yourmodem and serial mouse. If your modem is onCOM1, the mouse can only use COM2 orCOM4. If your modem is on COM2, themouse can only use COM1 or COM3.

Remote CommunicationsTroubleshooting Modem Communications


• Run the Terminal program (located in the Win-dows Program Manager/Accessories group) toensure the modem is configured correctly forWindows. To do so:

• Exit PRISM4 Remote, then exit allother applications except the ProgramManager.

• Run the Terminal program and selectthe Settings menus Communicationsoption (to ensure the correct Com Portsetting).

• Type the command “AT” (without thequotation marks) and press < EN-TER> . If everything is correct, OKor 0 (zero) should appear on the mo-dem terminal screen.

¾ If you do not see the text echoed back to thescreen as you type the command, use theSettings menus Terminal Preferences op-tion to select Local Echo as the TerminalMode.

If the modem does not work in Terminal (OK or 0 is notreturned after typing AT), try the following:

• Disable 32-bit file access. To do so, select theControl Panels 386 Enhanced, choose the Vir-tual Memory button, choose the Change but-ton, then clear the Use 32-Bit Disk Accesscheck box.

• In the Windows directory, open the SYS-TEM.INI file and check the [Boot] section forthe proper communications driver. Search forthe line that reads, COMM.DRV= . The lineshould read, COMM.DRV= COMM.DRV, un-less the COMM.DRV on the right side indicatesa third party driver (Windows FAX or communi-



cation programs are applications that might re-place the standard driver with one of their own).If COMM.DRV is set to anything other than thestandard driver (COMM.DRV), change the lineto read COMM.DRV= COMM.DRV.

¾ Ensure the line is not commented out (com-ments in the .INI files are defined with asemicolon at the beginning of the line).

• Also, ensure the COMM.DRV file in the Win-dows SYSTEM subdirectory is dated 3/10/92and has a file size of 9280 bytes (for Windows3.1), or is dated 11/1/93 with a file size of 5968bytes (for Windows for Workgroups 3.11). Ifthe date or size is incorrect, perform the nextstep. Otherwise, exit all programs and restartWindows.

• Quit Windows. Then, use the EXPAND utilityin the Windows directory to reinstallCOMM.DRV from the Windows Setup disks tothe WINDOWS\SYSTEM directory. To do so,type the following from a DOS prompt:

expand a:\comm.dr_ c:\windows\system\comm.drv

If the Terminal program prompts that the COM port is notsupported, or is being used by another device, the problemmight be with the computers configuration. Check for:

• Any TSR programs that are using the COM port.

• Another Windows program that is using theCOM port is currently running.

• Interrupt conflicts with the COM port and an-other hardware card such as a network card.

Appendix GIntroduction to the Triax

Accelerometer Sensor

Overview

The Triax Accelerometer Sensor automatically sequencesthrough three measurements for the sensor location (onefor each axis monitored by the triax accelerometer sen-sor). This application requires an external triax mod-ule/cable assembly and a triax accelerometer sensor. Atriaxial MPA ROUTE must be created in PRISM4 to ac-commodate the triax interface.

During data collection, the triax module/cable assembly’sLED display indicates which axis is being monitored.

Red - Axis 2

Green - Axis 3

Yellow - Axis 1

How to Mount the Triax Accelerometer Sensor

Triax mounting configuration factors to be considered are:mounting location, accessibility, temperature, and orienta-tion.

CMVA 60 Microlog G - 1User Manual change 01

¾ The triax accelerometer sensor’s axes are la-beled Axis 1, Axis 2, and Axis 3. The useris responsible for matching and assigning alabeled axis to a measurement orientation(i.e. horizontal, vertical, axial).

To collect valid measurements, the triax-sensor must al-ways be oriented in the same direction for all measure-ments at the same location.

¾ One axis of the triax accelerometer sensormust be aligned with the shaft centerline.

Figure G - 1.Mounting the Triax Accelerometer Sensor.

Introduction to the Triax Accelerometer SensorHow to Mount the Triax Accelerometer Sensor

G - 2 CMVA 60 Micrologchange 01 User Manual

For example, if the machine is mounted horizontally, thenmount the triax-sensor in the vertical direction to the shaftso Axis 2 is always pointing in the axial direction, Axis 1in the horizontal direction, and Axis 3 in the vertical direc-tion. If a vertical mounting is not possible, mount thetriax-sensor in the horizontal direction to the shaft. Pleasenote that now the horizontal and vertical axes are reversedfor this measurement POINT.

There are three basic mounting methods for the Triax-Sen-sor:

• permanent screw mount• studs with adapters

• magnet base mount

Permanent Mount with ScrewScrew mounting results in the widest frequency measure-ment range. It is recommended for permanent monitoringsystems only, higher frequency test, and harsh environ-ments.

¾ Before drilling into a machine housing orany item being prepared for mounting, it isimperative to know wall thickness and depthconstraints (i.e., mounting bolts, bearings,or other items) that might be behind themounting surface. SKF is not responsiblefor damage to items as a result of thesemounting instructions.

The mounting point on the structure should be faced 1.1times greater than the area of the sensor’s mounting sur-face. For measurements involving frequencies above 1kHz, the surface should be flat within 0.001’’ (.025 mm)and have surface texture no greater than 32 micro-inches

(0.8 µm). The tapped hole must be perpendicular to themounting surface and at least two threads deeper than theremaining threads of the screw.



Studs and AdapterStud mounting is ideal for enabling temporary or periodicvibration measurements for moderate frequency ranges.

Stud Installation Instructions

¾ Before drilling into a machine housing orany item being prepared for mounting, it isimperative to know wall thickness and depthconstraints (i.e., mounting bolts, bearings,or other items) that might be behind themounting surface. SKF is not responsiblefor damage to items as a result of thesemounting instructions.

CMAC9600-02 Tool Kit for M8 1.25 stud

3/8 inch or larger electric drill

Adjustable wrench or 7/8 in. open-end wrench• Select location for mounting - Inspect for possi-

ble items behind the mounting area. For best re-sults, placement should be as close to thebearing load zone as possible.

• Prepare surface - Within a 2-inch-square area,chip away loose paint, remove dirt, and grindthe surface flat and clean with a hand tool.

• Determine depth for mounting studs - Threadsmust be at least 6mm (.236 in.) deep. To markthe depth, place the drill bit next to the stud’smounting post and place electrical tape aroundthe drill bit to indicate the desired depth (or, ifavailable, use a depth gauge).

• Begin drilling - In the 2-inch-square area’s cen-ter, mark the hole location with a center punch.Start by drilling a small pilot hole with a 6.7mmdrill bit for the M8 X 1.25 thread or a #3 drillfor the 1/4-28 thread, then enlarge the pilot holewith the CMAC9600-06 drill bit (M8 1.25), orthe 9600-03 drill bit (1/4-28). The hole shouldbe perpendicular to the surface.

• Insert pilot - Insert the CMAC9600-08 pilot(M8 1.25) or the CMAC9600-05 pilot (1/4-28)into the CMAC9600-09 counter bore. The pilotshould be mounted flush to the fluted cuttingedge. Tighten the pilot in the counter bore us-ing the supplied wrench.



• Spot face mounting area - Using the pilotedcounter bore, spot face the recess until smooth

(32µin .0.8µm), until the surface is approxi-mately 1 inch in diameter.

• Tap hole - Use the CMAC9600-07 tap (M81.25) or CMAC9600-04 tap (1/4-28) to handtap the hole to the desired thread depth.

Important: Do not bottom-out or over torque the tap.

• Clean - Clean the spot faced surface and thestud with alcohol, CHEMLOKTM primer, or asimilar solvent. Use a lint free rag and cleanvery thoroughly. Allow to set a few minutes toallow the cleaning solvent to evaporate.

• Apply adhesive (optional, not suggested unlessstud is to be a permanent installation) - A two-part acrylic adhesive is required. Use SKFCMCP210 acrylic adhesive or a 460/17 acrylicproduct. Remove the divider attached to the ad-hesive pack. Thoroughly mix the two-part adhe-sive together for one to two minutes, stretchingboth sides along a table’s edge. Coat the stud’sthreads and bottom with the adhesive.

• Connect the adapter to the bottom of the triax-sensor with the supplied L/4-28 screw. Forproper orientation, connect the stud to the sen-sor’s adapter before tightening the stud to thesurface.

• Orient the triax-sensor in the proper orientationas outlined above. Then disconnect the adapterfrom the stud without changing its orientationand tighten the stud with the 1/4-28 x 3/4 inscrew to the surface. The triax-sensor will al-ways point in the correct direction, as the adapt-er can only connect one way.

• Tighten - Mount and tighten the stud (24 in.-lbs/ 2.9 Nm). Be careful not to over torque.



Magnet Mounting BaseA magnet base with a threaded hole to accept a stud-mount triax-sensor is a convenient means of providing aquick or temporary mount. This method results in a re-duced meaurement frequency range compared to screw orstud mounts. The machine mounting surface should berelatively smooth and flat. Again, always place the triax-sensor at the same location with the same orientation to ob-tain valid measurements.

Triaxial MPA ROUTE Setup

> To set up a Triaxial MPA ROUTE:• In your PRISM4 software, access the POINT

Setup screen. The POINT Setup screen’s De-scription field is used to identify triaxial MPAPOINTs. The first 4 characters in the Descrip-tion field identify the triaxial MPA group towhich the POINT being configured belongs.For MPA POINTs, the first character is always"@". The @ character must be followed bythree alpha/numeric characters that identify thegroup of triaxial MPA POINTs.
