2-2. Mounting/Replacing the sensor
When replacing the sensor, take care for the following points.
・ After replacement of the sensor, be sure to perform the sensor calibration. If not, the
reading may be deviated.
・ If the unit is not used for a long period, be sure to perform the sensor calibration
before use.
・ Replace the sensor if you can no longer perform AIR calibration or when the reading
is unstable.
・ Sensor replacement shall be done at power off condition.
[Replacing the sensor]
1)
Verify that the unit is off.
2) Turn the rubber guard on the sensor retainer counterclockwise until yellow line on the
rubber guard will indicate the proper amount of rotation by lining up with a yellow line on
the instrument body that indicates “UNLOCK”.
3) Pull the sensor retainer away from the instrument body.
4) Pull the old sensor out from the sensor retainer.
5) Replace the sensor with new one. In this case, match up the concave part of sensor
connector with the convex part of sensor mounting.
6) Align the yellow line on the sensor retainer’s rubber guard with the “UNLOCK” line on
the case, insert it deeply and turn the rubber guard to the “LOCK” line.
