Sensor may have a build-upof dirt or oily material onelectrode plates.2. Sensor is not immersedcorrectly.3. Sensor is faulty.4. Faulty instrument.5. k-factor incorrectly set ifusing user-selectable k factorsensor.Clean sensor, as per the instructionsdetailed in section 17.3.Clean sensor, as per the instructionsdetailed in section 17.3.Immerse sensor correctly, with adequateclearance to the floor and walls of thevessel, as per section 17.2.Return sensor to factory for repair orreplacement.Return to factory for repair.Set the correct k-factor, as per sections 3.7,4.7, and 5.6.16.4 Temperature TroubleshootingSymptom Possible Causes RemedyTemperature inaccurate andcannot be calibrated.Displays flashing “OVR O c”when temperature probeplugged in.1. Faulty connector.2. Faulty temperature sensor.1. Faulty TEMP socket.2. Faulty temperature probe.Check the connector and replace ifnecessary.Fit new temperature probe, part number121245, or combination Conductivity &Temperature sensor.Return the instrument to the TPS factory forservice.Fit a new temperature probe, part number121245, or combination Conductivity &Temperature sensor.
