AINTENANCE
In order to maintain the specified accuracy this device, both its sensors must 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, or if exposed to concentrations above its rated maximum, a sensor may fail prematurely.
During normal operation both sensors are regularly tested to detect common failures. If a failure is detected, the
front panel status LED for that sensor will blink red and its concentration-reporting analog output will stay at 20
mA until the sensor is replaced.
