Option DescriptionInterferences enabled duringcalibrationMake sure this is disabled by unchecking the box.Zero calibration bottle Make sure this is disabled by unchecking the box as it is not relevantfor this sensor.2. Exit from the configuration screen by pressing OK.3. Select Calibration and perform a manual zero calibration as described in Zero calibrationon page 23. For high range sensors perform an additional 100% humid air calibration asdescribed in 100% humid air calibration (high range sensors only) on page 23.9.2.2 Manual calibrationManual calibrations can be made at any time by following these steps:1. Remove the sensor from the sample line.2. Rinse the sensor head with clean water.3. Wipe the sensor head with a clean soft tissue to remove any excess moisture.4. If using the supplied calibration device insert the sensor into the sensor holder on top of thecalibration device. If not using the calibration device insert the sensor into the flow chamber.5. Flow the calibration sample through the calibration device or flow chamber as applicable. If usingthe calibration device fully open the valve on the pressure reducer to give a gas flow rate of0.1 L/min. If you are not using the supplied calibration device with pressure reducer the maximumallowable inlet pressure must be no more than 2 bar absolute.6. Configure the calibration as described in Calibration configuration on page 22.7. Start the calibration as described in Zero calibration on page 23, 100% humid air calibration(high range sensors only) on page 23 or High level adjustment on page 24 depending on thepreferred calibration method.9.3 Calibration configurationNote: This option can also be invoked by pressing the Modify button in either the Zero calibration or High leveladjustment calibration screens.1. From the Main menu, select Calibration followed by Gas sensor and then Configuration.Option DescriptionAuto-calibration Not available for this sensor.Manual-calibration When Auto-End is enabled a manual calibration will complete automatically whenthe parameters defined in Stop parameters are reached. Press on Configure to setthe manual calibration parameters. If the calibration fails, the previous calibrationparameters remain unchanged and a warning message displayed.Hold duringcalibrationIf checked this keeps the last measured value and stops updating the outputs duringthe calibration or verification process. This avoids sending invalid information to anyconnected device. At the end of a calibration, this hold remains on for a further10 minutes to allow the system to stabilize.Interferencesenabled duringcalibrationThis option enables the Chlorine or Salt interference during calibration. This optionmust be used if there is chlorine in the calibration solution and if the chlorineinterference correction is enabled during measurement.22 English
