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 measuring instrument is used
normally.
> Check the additional filter (visually) periodically for
contamination 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. Loosen the additional filter from the hose connection.
4 Plug the new filter (0133 0010) into the hose connection.
5. Attach the service cover and engage it in place.
