8 TroubleshootingSymptom Possible Cause Recommended ActionSlow recoveryAt installation – extended exposure to airAt installation – sensor housing not properlytightenedContinue purging sensor with preferably N2 zero gasor sample gas with low ppm oxygen concentrationCheck and tighten bolt in center of bottom section ofsensor housing, purge sensor as aboveHigh O 2 readingafter installing orreplacing sensorHigh O 2 readingSamplingResponse time slowO 2 reading doesn’tagree to expected O 2valuesAir leak in sample system connection(s)Abnormality in zero gasDamaged in service - prolonged exposure toair, electrolyte leakSensor nearing end of lifeAnalyzer calibrated before sensor stabilizedcaused by:1) Prolonged exposure to ambient air, worseif sensor was unshorted2) Air leak in sample system connection(s)3) Abnormality in zero gasFlow rate exceeds limitsPressurized sensorImproper sensor selectionAbnormality in gasAir leak, dead legs, distance of sample line,low flow rate, volume of optional filters andscrubbersPressure and temperature of the sample isdifferent than span gasAbnormality in gasReplace sensor if recovery unacceptable or O 2reading fails to reach 10% of lowest rangeLeak test the entire sample system:Vary the flow rate, if the O 2 reading changesinversely with the change in flow rate indicates an airleak - correct source of leakQualify zero gas (using portable analyzer)Replace sensorReplace sensorAllow O 2 reading to stabilize before making thespan/calibration adjustmentContinue purge with zero gasLeak test the entire sample system (above)Qualify zero gas (using portable analyzer)Correct pressure and flow rateRemove restriction on vent line or open SHUT OFFvalve completelyReplace GPR/PSR sensor with XLT sensor when CO 2or acid gases are presentQualify the gas (use a portable analyzer)Leak test (above), reduce dead volume or increaseflow rateCalibrate the analyzer (calibrate at pressure andtemperature of sample)Qualify the gas (use a portable analyzer)29
