6.5 Replacing the particulate filter
If the particulate filter appears black, especially on the inner surface (see adjacent example), it has to be replaced
immediately. In this way gas flow is not obstructed.
6.6 Replacing the gas sensors
The gas sensors of the instrument shall be periodically replaced (see the following table) with new or recalibrated
sensors.
The user can easily perform this replacement operation according to the following instructions:
1
Undo the two fixing screws on
the sensor compartment cover.
2
Remove cover to gain access to the sensor compartment,
then grab the sensor assembly and carefully pull it out.
