4. User Manual SENSOR REPLACEMENT When the instrument can no longer be calibrated by adjustment of the CAL control it is possible that the Oxygen Sensor unit is exhausted and should be replaced The ANALOX 9212 4 Sensor Assembly has a life of approximately 3 years in normal air but this will be reduced if it is constantly exposed to higher concentrations of Oxygen Conversely if the sensor is normally exposed to lower concentrations of Oxygen its life may be extended The sensor must be replaced with an Analox Oxygen sensor type 9212 4 as this sensor is especially manufactured for this instrument There are no serviceable parts in the sensor and cable assembly the entire unit must be replaced The sensor in the 101 D2 is an electrochemical device and contains a caustic electrolyte Always check to make sure that it is not leaking and do not allow it onto any part of your body or clothing In the event that you do come into contact with the electrolyte wash the contaminated part with copious amounts of water see safety information WARNING If after handling the sensor you fingers or other parts of your body feels slippery or stings wash with a lot of water If stinging persists get medical attention Document ref 1D2 800 01 January 2009 Page 6 AANALOX looking after the air YOU breathe ANALOX 101D2 Portable Oxygen Monitor User Manual 8 0 TROUBLE SHOOTING SYMPTOM REASON SO
