Replacing additional filter
The additional filter provides added protection should problems occur with the particle
filter in the flue gas probe. The additional filter is very rarely contaminated if the measur-
ing instrument is used normally.
Check the additional filter (visually) for contamination from time to time and replace it
if necessary.
1 Place the measuring instrument on its front.
2 Remove the service cover: Take hold of it at the
markings (arrows) using the index finger and
thumb, press slightly, fold up and remove.
3 Release the additional filter from the hose connec-
tions.
4 Fit a new filter (0133 0010) on the hose
connections.
5 Attach the service cover and engage it in place.
