<Replacement of Gas Sensor>
Our service engineers need to replace and adjust the sensor. Please contact RIKEN KEIKI.
NOTE
If adjustment to the standard gas concentration value fails even with the maximum sensitivity, it
indicates that the gas sensor has come to the end of its life. The gas sensor needs to be replaced.
After replacing the gas sensor, electrical adjustment and calibration using the standard gas are
necessary.

For the stable operation of the detector and safety, ask a qualified service engineer to take care of
replacement of the parts. Request the operation check from RIKEN KEIKI.
