Printout Configuration

PurposeThis menu item enables you toconfigure individual printout formats.With the formulation, totalizing andstatistics application, you can also define the values to be included on the total printout when the MR key is pressed.

Under “Setup > Printout > Application-defined output > Configured printout”,you can configure individual, compo-nent or total data records that containthe items in each application that areavailable for printouts. Configure theseprintouts after you have configured theapplications, because some entries inthe data record depend on the particular application.

Features– Maximum items in a data record: 60

– Separate configuration of printout formats for individual weights, components, total, backweighing andstatistics

– Individual printout generation: press the r key

Automatic printout of application data:e.g., results from animal weighing ordensity application (Setup menu: Appli-cation 1: Density: Printout: All data) OKvalues from checkweighing application,time-controlled printouts, 2nd tarememory

– Component printout: For results from totalizing, formulationor statistics applications, press M+ or M- (Setup: Application 3: ...,Printout of individual components: On)

– Total printout: For totalizing,formulation or statistics applications,press MR

– Backweighing printouts or records:automatically generated after back-weighing or manually by pressing ther key when the result is displayed at the end of backweighing

– Statistics printout or output:To generate, press the r key whenthe statistics are displayed

Printouts for Differential Weighing:These printouts can be generated asstandard or configured (user-defined)reports.

You can configure the following printouts:

– Individual printout

– Backweighing printout

– Statistics printouts

Printouts are generated in one of two ways:

– at the request of the user by pressingthe r key (print on request)

– automatically, if configured in theSetup menu [Application parameters:Application 1: Differential weighing:Generate printout: Auto]

You can turn off automatic printoutgeneration in the Setup menu [Application parameters: Application 1: Differential weighing:Generate printout: None]

– Data records are deleted after youhaved switched to a different applica-tion or activated or de-activated anextra function in the applicationparameters of the Setup menu

– A new pick list for a data record is created based on the currently activeapplication programs and extra functions

– Printout items can be deletedindividually

– No printout is generated when the following setting is configured:Setup: Printout: Line format: For raw data (16 characters)

General Instructions for Analytical Weighing withWeigh Cells

Handling of Samples and Containers Samples should be acclimatized to thetemperature of the weigh cell to avoidnegative effects on results, such as measurement errors and fluctuationscaused by air buoyancy resulting fromconvection currents across the surfaceof the sample.

These negative effects increase as the volume and/or surface area of thesample increases. For this reason, thesize of the container should be appro-priate for the sample.

Samples and containers should not betouched by the operator’s hands, as thehygroscopic effect of fingerprints andthe effect of the hand’s temperaturecan influence the measurement results. Samples must be applied very carefully,whether manually (using a forceps) orautomatically (by a robot or filling system).

When designing a draft shield device,steps must be taken to keep theincrease in temperature within theweighing chamber to a minimum (e.g., using a bypass).

Weighing Electrostatically Charged Samples or Containers If a sample or container is electrostaticallycharged, significant errors may result dur-ing weighing. Materials with low conduc-tivity, such as glass, plastic or filters, areparticularly susceptible to static electricity(resulting, e.g., from friction) because theweighing pan can discharge the static elec-tricity only very slowly.

The result is a force action between thecharge on the sample and the permanentlyinstalled parts of the weigh cell. This causes the readout to fluctuate constantly.

Ionization can be applied to make the airaround the sample conductive. This allowsthe charge to be compensated through the air, or discharged through the ground(grounded).

Aside from purely mechanical solutions(e.g., using a special weighing pan toshield the system), bombarding the samplewith ions of opposing polarity to neutral-ize the surface charge is one of the mosteffective methods for eliminating staticelectricity. Sartorius can provide ionizationdevices for installation in weighing systems.

The area around the weigh cell can alsocontain charges that negatively affect theaccuracy of weighing results. Appropriatesteps taken in the design of a draft shield device can counteract such effects.

Weighing Magnetic or MagnetizableSamples For technical reasons, the use of magnetiz-able materials in the manufacture of weigh cells is unavoidable, primarilybecause the operating principle of high-resolution weigh cells is based on compen-sation of the load through magneticforces.

When weighing magnetic or magnetizablesamples or containers, interaction betweenthe sample or container and certain partsinside the weigh cell may have a distortingeffect on the weighing results.

To keep such effects to a minimum, we recommend increasing the distancebetween the sample/container and theweighing system using a non-magneticmaterial. The force is reduced quadraticallywith the increase in distance.

Magnetizable or magnetized samples andthe weigh cell itself interact with magneticfields and magnetizable or magnetizedparts in the area surrounding the weighingsystem. The system can be shielded fromexternal magnetic fields to some extentusing (soft magnetic) plates.

Calibration, Adjustment, Linearization

PurposeCalibration is the determination of the difference between the weight readout and the true weight (mass) of a sample. Calibration does not entailmaking any changes within the balance.

Adjustment is the correction of this difference between the measured valuedisplayed and the true weight (mass) of the sample, or the reduction of the difference to an allowable level withinmaximum permissible error limits.

Linearization is the procedure used to eliminate the deviation from weightreadout plotted on the balance’s idealcharacteristic calibration curve and theactual weight readout. In other words,linearization reduces the amount oferror of a weight displayed to its maxi-mum permissible error limits. The idealcharacteristic curve is a straight lineplotted between zero load and maxi-mum load.

FeaturesYou can configure whether the calibration mode

– will be activated according to the specific setting (external/internal) or

– can be selected by the user after pressing the Cal soft key:Selection mode.Your balance can be calibrated exter-nally: (Balance menu: CAL key function;menu item Ext. cal./adj.;factory-def. wt. orExt. cal./adj.; user-defined wt.; or internally: (Internalcal./adjustment).

Adjustment can be performed– automatically following calibration:Cal., then autoadjust. or

– if desired, the adjustment operation canbe started manually after calibration:Cal., then manualadjust

Linearization is performed if you have selected Internal linearization in the Setupmenu or you have set this using theSelection mode.

You can have the balance automaticallydisplay an adjustment prompt after acertain time interval has elapsed sincethe last calibration/adjustment or whenthe ambient temperature changes by a defined amount.

You can also configure the balance to perform calibration and adjustment automatically (isoCAL) when the pre-settime and/or temperature limit isreached On and reset application and Onwithout resetting app.

You can have the calibration/adjust-ment results documented in anISO/GLP-compliant printout.

isoCAL:Automatic Calibration, Adjustmentand Linearization

First set either On and reset theapplication, isoCALand linearization on or On without resettingthe app. (factory setting) in the “Setup: Balance/scale functions”menu.

The “isoCAL” display automaticallybegins flashing if the ambient temperature changes in relation to thetemperature at the time of the last calibration/adjustment, or after a defined time interval has elapsed. The balance is telling you that it wantsto adjust itself.

This automatic calibration and adjust-ment prompt is activated when:

– The change in temperature is greaterthan1.5 Kelvin or the elapsed time interval is greater than 4 hours

– The balance Setup mode is not active

– No number or letter input is active

– The load has not been changed withinthe last 2 minutes

– The balance has not been operated within the last 2 minutes

– The load on the balance does notexceed 2% of the maximum capacity.

– When you turn on the balance after it has been disconnected from power (only on verified balance)

When these requirements are met,C is displayed in the line for measuredvalues.

If the balance is not operated and the load is not changed, internal calibration and adjustment will startafter 15 seconds have elapsed.

Automatic Calibration and Adjustmentat Set Times *In the Setup menu, you can now enterup to three different times of day forautomatic calibration/adjustment (seemenu tree on page 45). When one of these times is reached, the balancedisplays the flashing calibration prompt(“isoCAL”). Calibration/adjustment isnot performed if the balance is

– off (standby) or– in the Setup mode at the time set for

calibration.

If the balance is being operated at the time set for automatic calibration/adjustment, the calibration/adjustmentsequence will not be prompted or performed afterwards.

Automatic calibration/adjustment is prompted at set times when:

– The set time is reached

– The balance Setup mode is not active

– No alphanumeric input is active (e.g., equation for calculation)

– The load has not been changed withinthe last 2 minutes

– The balance has not been operated within the last 2 minutes

– The load on the balance does notexceed 2% of the maximum capacity

* = does not apply to verified balances

In the Setup menu, you can configurethe balance so that after calibration andadjustment

– the application program is restarted On and reset the application

– isoCAL and linearization are activatedand the application program must berestartedisoCAL and linearization on

– the application program remains at itsprevious status On without resettingthe app.

Also in Setup, you can configure thebalance so that it displays a calibrationprompt, but does not perform the calibration/adjustment functions automatically:Only adjustment prompt

Switching off the isoCAL Function on Verified ModelsIf the equipment has been disconnectedfrom power, please observe the follow-ing:

– Directly after switching the equipmenton and before performing any weighingoperations, calibrate/ adjust the weighcell,

– perform calibration adjustment againafter 30 minutes, and

Repeatability Test (reproTEST)

DefinitionRepeatability is the ability of the balance to display identical readouts when it isloaded several times with the same weightunder constant ambient conditions. Thestandard deviation for a given number ofmeasurements is used to quantify the repeatability.

PurposeThe “reproTEST” function automaticallydetermines the repeatability (also called“reproducibility”) of results (based on6 individual measurements). In this way, thebalance determines one of the most impor-tant quantities in relation to the place ofinstallation. The results are displayed withthe balance’s accuracy.

PreparationTo calculate a piece count, the average weight of one piece must be known. This average piece weight can be entered into the Counting program in one of threeways:

– Enter the average piece weight using the numeric keys and store it;

– The last reference sample quantity entered is loaded and displayed when you turn on the balance. Place the same number of parts on the balance and initialize the Countingprogram;

– When the automatic initialization parameter (see previous page), is on (Setup: > Printout:Application-defined output: Autoprint upon initialization: All values), the balance goesinto the “counting” mode when you turn it on and loads the last average piece weightand corresponding reference sample quantity that were entered or calculated.

Reference Sample UpdatingYou can have the average piece weight updated during counting (with the piece count displayed) if “AWP update” is set to “manual” or “automatic” in the Setup menu. Manual updating can only be performed when the Update soft key is displayed. Reference sample updating must be completed before using an application program fromApplication 3.

The Update soft key is displayed when:– the balance has stabilized (stability symbol displayed)

– the current piece count is not more or less than double the original piece count

– the current piece count is more than 100

– the internally calculated piece count (e.g., 17.24) differs from the nearest whole number(in this case: 17) by less than ±0.3

Reference updating can be repeated several times with an approximately doubled piece count.

Equations Used to Determine Density

Buoyancy: Rho = (Wa · (Rhofl – LA)) / ((Wa – Wfl) · Corr) + LA

For the buoyancy method, a factor of 0.99983 (factory setting) is used toallow for the buoyancy caused by the bars of the sample holder of the YDK01 (LP) Density Determination Kit. This factor is yielded by allowing for thisequation:

buoyancy of bars/wires = 2 · d2 / D2 (Wa – Wfl)

The equation considers the following variables: the number of bars or wires,the bar/wire diameter of the sample holder, and the inner diameter of thevessel used.

The correction factor 0.99983 is yielded by 1 – 2 · d2 / D2

where: 2 = number of wires/barsd = bar diameter (0.7 mm) for YDK01D = inner diameter of the vessel (76 mm) for YDK01

If you are using different vessels or other density kits, press the Param. soft key to enter any necessary changes to this calculationfactor.

To determine the density of a solid according to the buoyancy method withour YDK 01 (LP) Density Determination Kit, make sure to use the beaker witha 76 mm diameter.

Displacement: Rho = (Wa · (Rhofl – LA)) / (Wfl · Corr) + LA

For the displacement method, a factor of 1.00000 (factory setting) is used toallow for the buoyancy caused by a wire suspended in the liquid.

If you are using different vessels or other density kits, press the Param. soft key to enter any necessary changes in this calculationfactor.

The equation considers the following variables: the number of wires or bars,the wire/bar diameter of the sample holder, and the inner diameter of thevessel used.

This factor is yielded by: Corr = 1 – χ · d2 / D2

where: χ = number of wiresd = wire diameterD = inner diameter of the vessel

Rhofl = density of the liquid causing buoyancyWa = weight of sample in airWfl = weight of the sample in liquid/buoyancy of sampleCorr = correction for buoyancy produced by the immersed

wires or bars of the sample holder:– = 0.99983 for the buoyancy method– = 1 for the displacement method

LA = correction for air buoyancy = 0.0012 g/ccm

Pycnometer: Rho = (Wa · (Rhofl – LA)) / (Wfl + Wa – Wr) + LA

where: Rhofl = density of the reference liquidWa = weight of the sampleWfl = weight of the reference liquidWr = weight of sample + the reference liquidLA = correction for air buoyancy = 0.0012 g/ccm

Differential Weighing

PurposeThis application enables you to com-pare samples before and after a giventreatment (such as drying or ashing)and determine the difference in weight.

There are different procedures availablefor this application:

– Collect all data (tare, initial weight, andbackweighing result) for each sampleindividually (menu setting “Weighingsequence: Individual weighing”)

– Save the tare weights and initial weights for all samples first, then perform backweighing (menu setting“Combined weighing”)

– Save the tare weights for all samplesfirst, then determine the initial weightof each sample and, finally, performbackweighing (serial weighing)

Features– 4 different sequences for measuring the

tare weights, initial sample weights andthe backweights (backweighing result):– Individual weighing– Consecutive individual

weighing– Combined weighing– Serial weighing

– Choice of weighing sequence by select-ing this parameter in the Setup menu or by pressing the Wg.seq soft key(if the “Weighing sequence key” optionis set)

– Perform up to 99 backweighing rou-tines on a single sample

– Differential weighing with or withouttare weighing (not necessary for meas-uring coatings or lamination layers)

– Define the number of decimal placesdisplayed for calculated results

– Define whether autosaving weight values is dependent on the stabilityparameter

– Define whether the minimum load forautosave is dependent on the display

– List function, withDisplay page for lots:Lists all lots (up to 100 max.) with the number of samples in each lot andthe processing status (tare weight,initial weight, backweighed residue(“backweight”)View, create, rename or delete lots generatedEnter or change a factor for calculationof results

Differential Weighing: Defining theWeighing SequenceYou can choose from among foursequences for measuring tare weights, initial sample weights andbackweighed residue (“backweight”)during differential weighing:

1. Individual WeighingTare weight, initial weight and back-weight are measured in that order.

2. Consecutive Individual WeighingSeveral individual weighing routines(see above) are performed in series.

3. Combined WeighingThe tare and initial weight, in thatorder, of each sample is measured first,then the backweight of each sample ismeasured.

4. Serial WeighingFirst the tare weight for each sample ismeasured, then the initial weight ofeach sample is measured in the sameorder that their tare weights were measured, and then all backweights are measured.

You can define the weighing sequencein the Setup menu or by pressing theWg.seq (if the “Weighing sequencekey” option is activated).

List Function for Differential Weighing

The list function has 4 display pages: one each for lots, samples, values and results.

Display Page for LotsThe display page for lots shows all of the lots that have already been created, as well as thenumber of samples in each lot and the processing status of the selected sample (tare, initialand backweight). On this display page you can create, rename, delete and print lots. You can also define a factor for calculation of loss; for instance, to have weight per unitarea calculated (such as grams per square meter). You can also enter a lot ID alphanumeri-cally to access a lot directly.

Display Page for Samples This display page shows the samples contained in a selected lot, as well as the processingstatus of the samples (tare, initial and backweight) and the sample IDs. You can also enter a sample ID alphanumerically to access a sample directly.

Display Page for ValuesThis display page shows the date and time of sampling, as well as the sample ID and the values measured, for a selected sample.

Display Page for ResultsThis display page shows the calculated values for a selected sample. These include back-weighed residue, loss, loss calculated using a factor, and the ratio values. The d symbol indicates the value that is selected for display immediately following a backweighing procedure. To change this setting, use the q and Q soft keys to move the highlight bar tothe desired value, and press l to confirm.

Display Page for StatisticsThis page shows the characteristic data for a lot (date; time; statistics on, for example, thebackweighed residue; number of samples) as well as the calculated values (mean value, standard deviation).

Air Buoyancy CorrectionG

PurposeThis application enables you to correctweighing errors that occur due to air buoyancy when you work with weightsof various densities.

You can use this application in combination with a program chosen from Application 2 (checkweighing, time-controlled functions) and onefrom Application 3 (totalizing, statis-tics).

Air buoyancy correction cannot be combined with the formulation and 2ndtare memory applications.

The air density value is required for calculation of the air buoyancy correc-tion factor. Because not every locationhas an air density of 1.2 kg/m3, thedensity of a particular location can bedetermined using the air densitydetermination routine.

FeaturesBuoyancy correction:

– Automatic initialization of this application and loading the density of a weighed object stored in the non-volatile memory, RhoW and the airdensity RhoA last saved; display ofRhoW in the line for text.

– Automatic start of air buoyancy correc-tion and display of the a symbol forcalculated values, if selected in theSetup menu (Setup: Auto-start applica-tion when power goes on: Yes)

– Input of the density of a sample or an object using the numeric keys andby pressing the RhoW soft key. This activates air buoyancy correction,if not yet activated.

– Input range for the density of a sample:0.1 g/cm3 – 22.5 g/cm3.

– Storage of density values (RhoW andRhoA) in the non-volatile memory.

– Deactivation of air buoyancy correctionby toggling to the “Weighing” mode(weighing without air buoyancy correction)

Air Density Determination:– To determine the air density, use the

special weight set, YSS45, which is available as an accessory. This weightset consists of one steel and one aluminum weight and is available withthe “Weight Specifications” certificate.The densities of the steel (8.0) and aluminum references (2.7) are presetvalues and cannot be changed.

– Determine the air density by– entering the density using the

numeric keys – entering the specifications for

steel/aluminum and weighing thesteel and aluminum weights (accessory: YSS45)

– If you enter an air density using the numeric keys, the reference values(density and weight) for steel and aluminum are deleted from the displaypage “AIR D. PARAMETRS.”

– After the air density has beendetermined and saved by pressing theStart soft key, the reference valuesare printed out

– Preset value for air density: 1.2 kg/m3

– Range for entering air density values:1.0 kg/m3 – 1.4 kg/m3.

– You can activate or deactivate air density determination in the Setupmenu, thus blocking access to this program routine.

– The air density is generally determinedin grams as the weight unit.

– If air density determination is deactivated,the air density RhoA will be displayedfor 2 seconds in the text line when youpress the RhoA soft key.

– After the air density has beendetermined, you can save the value, but this is not required

– You can block storage of the specifica-tions (references) in the Setup menu.(Setup: Application parameters: Application 1: Air buoyancy correction:Change steel/aluminum references)

– The density values on the display pagefor reference values are standard, inalterable values

Diagram for Air Buoyancy Correction

Equations for Air Buoyancy Correction

To determine the mass of a sample, its weight is multiplied by the following factor K:

K = (1 – RhoA / RhoST) / (1 – RhoA / RhoW)

where:

RhoA = air density [kg/m3]

RhoST = density of steel (8,000 kg/m3)

RhoW = density of the sample [kg/m3]

Air Density Determination

Equations for Air Density DeterminationThe balance uses the equation below to calculate the air density for steel and aluminum based on the reference weights supplied:

mA · WST – mST · WAL

RhoA = –––––––––––––––––––––––––––––––––mA · WST mST · WAL

–––––––––– – –––––––––––RhoAL RhoST

where:RhoA = air density [kg/m3]RhoAL = density of aluminum [kg/m3] RhoST = density of steel [kg/m3]mA = mass of aluminum mST = mass of steelWAL = weight value of aluminum WST = weight value of steel

The mass of aluminum is calculated according to the following equation:

mAL = MAL · (1 – 1.2 / 8000) / (1 – 1.2 / RhoAL)

where:mAL = mass of aluminum (specification)MAL = conventional mass value of aluminumRhoAL = density of aluminum [kg/m3]

The mass of steel is calculated according to the following equation:

mST = MST · (1 – 1.2 / 8000) / (1 – 1.2 / RhoST)

where:mST = mass of steel (specification)MST = conventional mass value of steelRhoST = density of steel [kg/m3]

You can obtain the air density value in one of two ways:

1. Numeric Entry of the Air Density

� Turn on the balance and select the “Application parameters” as described for Air Buoyancy Correction

� Start application for “Air buoyancy correction”: press Start

� Start “Air density determination”: press the RhoA soft key

� Use the numeric keys to enter the air density (1.0 – 1.4 kg/m3): 1 . 2 ... 0

� Save value for air density: press the RhoA soft key

� Exit the application for determining the air density: press the oo soft key

2. Weighing and Saving the Reference Weights for Steel and Aluminum

� See the example on the following pages

SQmin Function

PurposeTo display the allowable minimum sample quantity “SQmin” in accordancewith the United States Pharmacopeia(USP). According to USP guidelines, the uncertainty of measurement may not exeed 0.1 % of the sample quantitywhen substances are weighed with thehighest degree of accuracy for volumedetermination. This additional functionensures that weight results lie withindefined tolerance limits correspondingto the requirements of your qualityassurance system.

Features– The service technician will determine

the required minimum sample quantitybased on your quality assurance require-ments at the location where the balanceis set up. Afterwards, he will store thisvalue in the balance. This setting cannotbe changed by the user.Once he has finished programming the balance, the service technician willprepare a “Test in Accordance with theUSP” certificate, on which he will recordthe measurements and the minimumsample quantity for the balance. If youuse the SQmin function, you can be surethat the weight results will correspondto the specifications on the certificateand, therefore, USP guidelines.

– Displaying the minimum sample quantity:The value is shown in the next line for 4 seconds after the “SQmin” soft key ispressed orthe value is constantly displayed in placeof the bar graph.

– This function can be assigned to eitherthe fourth or fifth soft key from theright (F4 or F5). The soft key shouldthen be labeled with SQmin.

– If the minimum sample quantity has notbeen reached:The SQmin soft key will flash inversely.Weights will be marked with an asterisk“*” in the printout.

– Header of GLP-complicant records: Theminimum sample quantity entered for“SQmin” can be printed out in addition.

– The SQmin function can be used onlywhen the highest resolution for the basicunit of the balance has been set.

Interfaces

PurposeThe GPC… series balances have twointerfaces that allow weights and othermeasured values, calculated values andparameter settings to be output to a printer, PC or checkweighing display,etc. Control commands (for foot switchfunctions) and alphanumeric inputs(such as those from an online bar codescanner) can also be input in the balance via the two interfaces.

Features– GPC… series balances have two serial

interface ports:– Serial printer port (PRINTER –

Serial Out)– Serial communications port

(PERIPHERALS – Serial I/O)

– The serial printer port has a perma-nently installed 25-contact D-Subfemale connector (RS-232)

– The following printers can be con-nected to this printer port:– YDP02– YDP03– YDP01IS– YDP01IS Label– YDP02IS– YDP02IS Label– Universal– YDP04IS– YDP04IS Label

! You may need to use an external power supply to operate peripheral devices.

– In addition, the following equipmentcan be connected to the printer port:– Remote display– Hand switch– Foot switch– External checkweighing display– Bar code scanner*– Keyboard*

* using the YCC01-0024M01 adapter(see “Accessories”)

– The serial communications port hasa 25-contact D-Sub female connec-tor as a standard feature. This con-nector can be exchanged for eitherof the two female connectors below:– 12-contact round connector

(RS-485 for xBPI; RS-232 for SBI,xBPI)

– 9-contact D-Sub connector fordirect connection of a PC

– Both the 12-contact and the 9-contact female interface connec-tors are additionally equipped with a 5-pin male connector to directlyinterface an external bar code scanner or a keyboard.

– The serial communications port can beused in the following modes:– SBI– xBPI (BPI)

– The following equipment can be connected to this serial communica-tions port:– Printer not verifiable for legal

metrology in the EU– PC– Remote display– Hand switch– Foot switch– External checkweighing display– T-connector– Bar code scanner*– Keyboard*

* if the 25-contact D-Sub female connector is installed, you will needto use the YCC01-0024M01 adapter(see “Accessories”)

– Printouts generated from the applica-tion programs or by the configurableprint function can be output to the serial printer port or to the serial communications port or to both.

– If you have selected the automatic printmode, data will be output to the serialcommunications port; printouts generated by the application programswill then only be output to the serialprinter port.

– In the xBPI mode, the serial communications port can operate independently of the serial printer port(this means you can transfer data fromthe balance to a PC and use this PC tocontrol your balance while generatingprintouts via the serial printer port).

– In the SBI mode, you can use ESC commands from your PC to control thebalance via the serial communicationsport.

For printing an individual value onrequest, either by pressing the print keyr or by sending an ESC P printcommand, the particular menu settingdetermines which data port will beselected for data output.

Printouts

PurposeThis function enables you to print outweights, other measured values and IDs.You can format the printout to meetdifferent requirements.

FeaturesLine format: you can configure a dataID code with up to 6 characters at thebeginning of each of the values to beprinted

Weight ID: You can configure an extra line foridentification of each weighed or calculated value using the code S ID

Print application parameters:You can generate a printout of the values configured for initialization of an application before printing the measured results

ISO/GLP-compliant printout:You can print out parameters relating to the weighing conditions

Print animal weights:Application-defined, automatic printoutof animal weights or of animal weightsplus calculated weights after averaging

Optimizing interfaces:– Use the highest possible baud rate

– Turn off interfaces that are not in use

– Optimize the amount of data to betransfered

Configuring Printout FormatsFor a number of application programs,you need to set initialization values. All values upon initialization or only themain values can be automatically printedas soon as you have configured this inthe Setup menu: Auto printupon initialization

Weights and calculated values can beprinted as numeric values either with apreceding data ID code (numeric valuewith 22 characters) or without one(numeric value only 16 characters). See also the section on Line format in the chapter entitled “Data Output Functions”.

You can generate an ISO/GLP printoutalways or only for calibration/adjust-ment or turn off this option.

Generating an ISO/GLP PrintoutIn the Setup menu, you have a choiceof three settings:

– No ISO/GLP printout generated (Off)

– ISO/GLP printout generated only for calibration/adjustment (Only forcalibration/adjustment)

– Every printout is an ISO/GLP-compliantreport (Always on)

Auto print checkweighing results: automatic printout of a weight when it lies within the preset limits at stability

Auto print with time-controlled func-tions: automatic printout of weightsafter a preset time has elapsed or at a defined time Printout of intermediate or final evalua-tion from the application 3 memory(totalizing, formulation and statistics);generate by pressing the MR soft key

Generating Printouts Acceptable forLegal Metrology:You can configure the Setup menu of the balance to generate data recordsthat are acceptable for legal metrologyon a Sartorius printer:

– YDP02– YDP03– YDP01IS– YDP01IS Label– YDP02IS– YDP02IS Label– YDP04IS– YDP04IS Label

r (Print) KeyPressing this key causes the currentvalue shown on the display to be printedout (weight with unit, calculated value,alphanumeric readout)

Setting:Printout: Application-defined output or Automatic output of displayed value

Line FormatThe current value displayed can beprinted with a data ID code of up to 6 characters at the beginning of the line.You can use this data ID code, to desig-nate a weight readout as a net weight(N) or a calculated value as a piececount (QNT)

Setting:Setup: Printout: Line format: For otherapps./GLP (22 characters)

Sample IDYou can have each weighed or calculatedvalue that you print preceded by a lineof text containing numbers and/or letters. You can either print this IDimmediately as alphanumeric input(press r) or store it as the sample ID(S ID soft key) to be included on thenext printout, if the “For other apps./GLP (22 characters)” setting is config-ured.

Print Application ParametersYou can generate a printout of one ormore of the values configured for initial-ization of an application as soon as youinitialize the balance. This can includesuch values as nRef, wRef, pRef, etc.

Setting:Setup: Printout: Application-defined output: Auto print upon initialization

Auto PrintYou can have the weight readout printedautomatically1. This printout can begenerated after a certain number of dis-play updates2; you can also configurewhether or not the auto-print functionis dependent on the stability parameter3.The display update frequency dependson both the model of the balance andthe current operating status.

Serial Communications Port

PurposeThe GPC… balance has a serial commu-nications port (labeled “PERIPHERALS”)to which you can connect a computer,a remote display or an external check-weighing display.

You can use an on-line computer to change, start and/or monitor the func-tions of the balance and the application programs.

The communications port also providesdata output port lines for the over/undercheckweighing program. This port canalso be used to connect a hand or footswitch.

!Warning When Using Pre-wired RS-232 Connecting Cables

RS-232 cables purchased from othermanufacturers often have incorrect pinassignments for use with Sartorius bal-ances. Be sure to check the pin assign-ment against the chart before connect-ing the cable, and disconnect any linesmarked “Internally Connected” (e.g., pin6). Failure to do so may damage oreven completely ruin your balanceand/or peripheral device.

SynchronizationDuring data communication between thebalance and an on-line device (computer),messages consisting of ASCII characters aretransmitted via the interface. For error-freedata communication, the parameters forbaud rate, parity, handshake mode andcharacter format must be the same forboth units.

You can set these parameters in the Setupmenu so that they match those of the on-line device. You can also define parameters in the balance to make dataoutput dependent on various conditions.The conditions that can be configured aredescribed under each of the applicationprogram descriptions.

If you do not plug a peripheral device intothe balance interface port, this will notgenerate an error message.

HandshakeThe balance interface (Sartorius BalanceInterface = SBI) has transmit andreceive buffers. You can define thehandshake parameter in the Setupmenu:

– Hardware handshake (CTS/DTR)– Software handshake (XON, XOFF)

Hardware HandshakeWith a 4-wire interface, 1 more character can be transmitted after CTS(Clear to Send).

Software HandshakeThe software handshake is controlledvia XON and XOFF. When a device isswitched on, XON must be transmittedto enable any connected device to communicate.

When the software handshake is configured in the Setup menu, thehardware handshake becomes activeafter the software handshake.

The data transmission sequence is as follows:

Balance ––– byte –––> Computer(trans- ––– byte –––> (receivingmitting ––– byte –––> device)device) ––– byte –––>

<––– XOFF –––––– byte –––>––– byte –––>

…(Pause)

…<––– XON –––––– byte –––>––– byte –––>––– byte –––>––– byte –––>

Transmitting Device:Once XOFF has been received, it preventsfurther transmission of characters. When XON is received, it re-enables thetransmitting device to send data.

Receiving Device:XOFF is transmitted after the 26th character has been stored. To prevent too many control commands from beingreceived at one time, XON is not trans-mitted until the buffer is almost empty.

Activating Data OutputYou can define the data output parameterso that output is activated either when a print command is received or automati-cally and synchronously with the balancedisplay or at defined intervals (see applica-tion program descriptions and auto printsetting).

Data Output by Print CommandThe print command can be transmitted by pressing r or by a software command (Esc P).

Automatic Data OutputIn the “auto print” operating mode, data is output to the interface port without anextra print command. You can choose tohave data output automatically at definedprint intervals with or without the stabilityparameter. Whichever parameter youselect, the data will be output as the readouts appear on the balance display.The display update frequency depends onboth the model of the balance and the current operating status.

If you select the auto print setting, data will be transmitted immediately the moment you turn on the balance. In the Setup menu, you can configurewhether this automatic output can bestopped and started by pressing r.

Care and Maintenance

ServiceRegular servicing by a Sartorius technician will extend the service life ofyour balance and ensure its continuedweighing accuracy. Sartorius can offeryou service contracts, with your choiceof regular maintenance intervals ranging from 1 month to 2 years.

The frequency of maintenance intervalsdepends on the operating conditionsand your tolerance requirements.

RepairsRepair work must be performed by trained service technicians. Any attemptby untrained persons to perform repairsmay lead to hazards for the user.

Cleaning!Make sure that no dust or liquid enters

the balance housing

!Do not use any aggressive cleaningagents (solvents or similar agents)

§ Unplug the AC adapter from the walloutlet (mains supply)

§ If you have a data cable connected to the interface, unplug it from the balance

§ Carefully remove any sample residue/spilled powder using a brush or a hand-held vacuum cleaner

§ Clean the balance using a piece of clothwhich has been wet with a mild deter-gent

§ Use a commercially available glass cleaning agent to clean the draft shielddoors

§ After cleaning, wipe down the balancewith a soft, dry cloth

To remove the weighing pan and clean:§ Reach under the shield plate and lift it

together with the weighing pan off thebase to avoid damaging the weighingsystem.

!Make sure that no dust or liquid entersthe balance housing

§ Carefully remove spilled powder fromthe weighing chamber using a small carvacuum cleaner with a mini-hoseattached

§ To remove liquid spills, use blottingpaper

Safety InspectionIf there is any indication that safe operation of the balance with the ACadapter is no longer warranted:

§ Turn off the power and disconnect thepower cord from an electrical outlet(mains supply) immediately

> Lock the AC adapter and power cord in a secure place to ensure that theequipment cannot be used during thistime

Safe operation of the balance with theAC adapter is no longer ensured when:

– there is visible damage to the ACadapter or power cord

– the AC adapter no longer functions properly

– the AC adapter has been stored for arelatively long period under unfavorableconditions

In any of these cases, notify your nearest Sartorius Service Center or theInternational Technical Support Unitbased in Goettingen, Germany. Maintenance and repair work may onlybe performed by service technicianswho are authorized by Sartorius andwho

– have access to the required maintenance manuals

– have attended the relevant service training courses

We recommend that the balancetogether with the AC adapter beinspected by a qualified Sartorius service technician according to the following checklist:

– Leakage current <0.05 mA measured by a properly calibrated multimeter

– Insulation resistance >7 megaohms measured with a constant voltage of at least 500 V at a 500 kohm load

The duration and number of measurements should be determined by a qualified Sartorius service technician according to the particularambient and operational conditions for the AC adapter. Such inspectionshould be performed at least once a year.
