6. SensorCalibration
Sensorcalibrationcanbeappliedtoanewsensororanexistingonewithshiftedmeasurement.Underthis
conditionO2sensorshouldbecalibratedviaOPT100paneltoreadoutcorrectO2level.
Sensoroutputdecreasesto70%whenitslifetimeexpires.Youcaneasilyrecognizethisconditionwithvery
lowandunlogicalO2valuearound5%to10%.Calibrationdoesntcorrectthiscaseandsensorshouldbe
exchangedforcorrectmeasurement.

2. ConnectcalibrationfittingintotheO2sensorviainstallingintothesensorinlet.
3. OpentheN2bottlevalveandsupplygastothesensor.

SENSOREXCHANGE:
Sensorispackedwithitscovertokeepitselectrolyteinpassivemode.Openthesensorcoverjust
before24hoursofinstallationandkeepitatambientconditionthatwilloperate.Passiveelectrolyte
willgetactivewiththiswayandstarttomeasurecorrectlyafterinstallationintotheOPT100panel.Do
notforgettonotesensorinstallationdateontothepanel.PleasecheckSENSORCALIBRATIONpart
fornewsensorcalibration.
