<Sensor Replacement Procedure>
Note: Do not turn the main unit upside down for a long time. (At most one minute as a guide)
After a sensor is replaced, energize the sensor for at least two hours before performing calibration.
Check that a replacement has the same type of gas, the same model and measurement range as the
sensor currently used.
Attaching an inappropriate sensor causes malfunction.
(1) Loosen the two screws at the bottom of the lower case and remove the battery unit.
(2) Loosen the two screws of the internal case cover and remove the cover.
(3) Remove the sensor connector and then pull out the sensor part by holding the knob of the sensor joint.
