Calibration / adjustmentNote: Function check activeCurrent outputs and relay contacts behave as configured

• Calibration: Detecting deviations without readjustment• Adjustment: Detecting deviations with readjustment

Caution:Without adjustment every dissolved oxygen meter delivers an imprecise or wrong output value! After replacing the sensor, the electrolyte, or the sensormembrane, you must perform a calibration!The resulting values must be taken over by an adjustment for calculating themeasured variables (measured value display, output signals)!

ProcedureEvery dissolved oxygen sensor has its individual slope and zero point. Bothvalues are altered, for example, by aging. For sufficiently high accuracy ofoxygen measurement, the meter must be regularly adjusted for the sensordata (calibration + adjustment).

Sensor replacement (First Calibration)After replacement of the sensor, electrolyte or sensor membrane, a “FirstCalibration” should be performed. During First Calibration, the sensor dataare stored as reference values for the statistics. The ”Statistics” menu of Diagnostics (Pg 68) shows the deviations of zero,slope, calibration temperature, calibration pressure and response time of thelast three calibrations with respect to the reference values of the FirstCalibration. This allows evaluation of the drift behavior and aging of thesensor.

Calibration/adjustment methods• Automatic calibration in water/air• Product calibration (saturation/concentration)• Data entry• Zero point correction


29

Recommendations for calibrationIt is always recommended to calibrate in air. Compared to water, air is a cali-bration medium which is easy to handle, stable, and thus safe. In the mostcases, however, the sensor must be dismounted for a calibration in air. When dealing with biotechnological processes which require sterile condi-tions, the sensor cannot be removed for calibration. Here, calibration mustbe performed with aeration directly in the process medium (e.g. aftersterilization). In the field of biotechnology often saturation is measured andcalibration is performed in the process medium (water) for reasons of sterility. For other applications where concentration is measured (water, waste water,etc.), calibration in air has proved to be useful.

Common combination: process variable / calibration modeMeasurement CalibrationSaturation WaterConcentration Air

If there is a temperature difference between the calibration medium and themeasured medium, the sensor must be kept in the respective medium forseveral minutes before and after calibration in order to deliver stable mea-sured values. The type of calibration pressure detection is preset duringparameter setting (Pg 47).

Adjustmentmeans that the values determined by a calibration are taken over.The values determined for zero and slope are entered in the calibrationrecord. (Cal record can be called up in the Diagnostics menu for the module,see Pg 68). These values are only effective for calculating the measured variables whenthe calibration has been terminated with an adjustment.A passcode ensures that an adjustment can only be performed by anauthorized person (Administrator).The Operator can check the current sensor data by a calibration and informthe Administrator when there are deviations.You can use the additional function SW 700-107 for granting access rights(passcodes) and for AuditTrail (continuous data recording and backupaccording to FDA 21 CFR Part 11).

Calibration / adjustmentAutomatic calibration in water

Automatic calibration in waterThe calibration value is always the oxygen saturation (referred to air).First, the slope is corrected using the 100 % value.

During calibration the analyzer is in function check mode.Current outputs and relay contacts behave as configured (BASE, Out, PID).

Caution!Ensure sufficient medium flow to the sensor (see Specifications of dissolvedoxygen sensors). The calibration medium must be in equilibrium with air.Oxygen exchange between water and air is very slow. Therefore, it takes arelatively long time until water is saturated with atmospheric oxygen. If thereis a temperature difference between calibration medium and measuredmedium, the sensor must be kept in the respective medium for severalminutes before and after calibration.

If you do not know the exact value of the rela-tive humidity of the air used, you can take the following standard values fora sufficiently precise calibration:• Ambient air: 50 % (average)• Bottled gas (synthetic air): 0 %

During calibration the analyzer is in function check mode.Current outputs and relay contacts behave as configured (BASE, Out, PID).Caution!The sensor membrane must be dry. Be sure to keep temperature and pres-sure constant during calibration. If there is a temperature difference betweencalibration medium and measured medium, the sensor must be kept in therespective medium for several minutes before and after calibration.

To do so, the currently measuredsaturation value of the process is stored by the measuring module. Directlyafterwards, a reference value is determined using a portable meter, forexample. The reference value is entered into the measuring system. From the difference between measured value and reference value, theanalyzer calculates the sensor slope. With low saturation values, the analyzercorrects the zero point, with high values the slope.During calibration the analyzer is in function check mode.Current outputs and relay contacts behave as configured (BASE, Out, PIDmodules).Caution!The reference value must be measured at temperature and pressure condi-tions similar to those of the process.

Zero correctionThe InPro6900 sensors have a very low zero current. Therefore, a zero cali-bration is only required for measurement of oxygen traces.If a zero point correction is performed, the sensor should remain for at least10 to 30 minutes in the calibration medium in order to obtain stable, non-drifting values. During zero point correction, a drift check is not performed.Zero point current of a properly functioning sensor is notably less than 0.5 %of air current.

AdjustmentTaking over the determined calibration parameters for calculating the measured value

Adjustmentmeans that the values determined by a calibration are taken over.The values determined for zero and slope are entered in the calibrationrecord (Cal record can be called up in the Diagnostics menu for the module). These values are only effective for calculating the measured variables whenthe calibration has been terminated with an adjustment.A passcode ensures that an adjustment can only be performed by anauthorized person (Administrator).The Operator can check the current sensor data by a calibration and informthe Administrator when there are deviations.You can use the additional function SW 700-107 for granting access rights(passcodes) and for Audit Trail (data recording and backup according toFDA 21 CFR Part 11).

NAMUR signals: Relay contactsFailure, maintenance request, function check

Failure is active when a value has exceeded (or fallen below, resp.) a preset ”Failure Limit Hi”or ”Failure Limit Lo”, when the measured value is out of range or in theevent of other failure messages. That means that the equipment no longeroperates properly or that process parameters have reached a critical value.Failure is disabled during “Function check”.

Maintenance request is activewhen a value has exceeded (or fallen below, resp.) a preset “Warning LimitHi” or “Warning Limit Lo”, or when other warning messages have been acti-vated. That means that the equipment is still operating properly but shouldbe serviced, or that process parameters have reached a value requiring inter-vention.Warning is disabled during “Function check”.

Function check is active: • during calibration• during maintenance (current source, meas. point maintenance)• during parameter setting at the Operator level and the Administrator level• during an automatic rinsing cycle.

As delivered, the floating relay outputs of the M 700 BASE are assigned tothe NAMUR signals:• Failure: Contact K4, normally closed contact (signaling current failure)• Maintenance request: Contact K3, normally open contact• Function check: Contact K2, normally open contact

Warning!Make sure that the maximum ratings of the relay contacts arenot exceeded even during switching!

Protective wiring of relay contacts

Relay contacts are subjected to electrical erosion. Especially with inductiveand capacitive loads, the service life of the contacts will be reduced. For suppression of sparks and arcing, components such as RC combinations,nonlinear resistors, series resistors and diodes should be used.

Information concerning relay contactsAs delivered, the relay contacts are suitable for low signal currents (down toapprox. 1mA). If currents above approx. 100 mA are switched, the goldplating is destroyed during the switching process. After that, the contactswill not reliably switch low currents.

Appendix:Minimum measuring spans for current outputs

The O2 4700(X) ppb module is a measuring module. It does not provide cur-rent outputs. Current outputs are provided by the M 700 BASE (basic device)or by communication modules (e.g. Out). The corresponding parametersmust be set there.

The minimum current span shall prevent that the resolution limit of themeasurement technology (± 1 count) is seen in the current.

Dissolved oxygen measurement in carbonated beverages(SW 700-011)Application-specific additional function for breweries

This additional function simplifies parameter setting since all steps notrequired for dissolved oxygen measurement in carbonated beverages areomitted. It simultaneously acts on all installed O2 modules (module software version 2.2 and higher).

Function principle:The following processes are automated by the additional function, i.e. allparameters required for the respective program step are set automatically.

During the filling process, for example, it must be ensured that as little oxy-gen as possible is dissolved in the beer to extent its shelf life.During oxygen trace measurement the sensor is operated with a very lowpolarization voltage (-500 mV). This results in low cross-sensitivity to CO2.

For a calibration in air, this polarization voltage is too low.It must be set to -675 mV and afterwards be reduced again to -500 mV formeasuring in the trace range.Be sure to wait long enough for the sensor to stabilize.

Opening and closing of valves causes pressure variations in the beer pipeswhich momentarily falsify the O2 signal. Therefore the input signal must beattenuated correspondingly to suppress transient interferences.
