If the sensor does not pass a full calibration, the sensor may need replacement. Do not use the

instrument until it passes a full calibration.

13. Replacing The Filter & Sensor

The sensor needs to be replaced when it is unable to be calibrated or behaves erratically. Also, the

filter should be inspected periodically, and it should be replaced if it shows signs of accumulated

dust, dirt, or debris.

One of the holes in the sensor cover has a clear plastic window. While the other holes allow

ambient air (and dirt, debris, etc.) to reach the filter, the window keeps the part of the filter under it

clean. As a result, it is easy to visually confirm that the filter needs replacement by simply

comparing the clean spot with the other spots.

Remove the front cover by using the tab end of the calibration cap or a flat-blade screwdriver to pry

it upwards from the slot. This exposes the sensor with its filter attached.
