In order to maintain the specified accuracy this device over its full operating range, its sensor should be calibrated 
at least every 6 months.  During calibration the sensitivity of the sensor is compared to its sensitivity during initial 
factory calibration.  If the sensitivity has fallen below the manufacturer’s specification, the sensor has reached the 
end of its operating life and must be replaced.  Contact Kele for a calibrated replacement module. 

In harsh environments a sensor may fail prematurely.  During normal operation the sensor is regularly tested to 
detect common failures.  If a failure is detected, the front cover status LED will blink slowly RED, the warning relay 
will be activated and the concentration-reporting analog output will stay at 4 mA until the sensor is replaced.
