ADDITIONAL INFO / IMAGES

Check the measuring cell cover seal (A) and re-
place, if required.

Reattach the measuring cell cover on the
measuring cell, close the clamp and fasten in
place with the Allen bolt (circle).

Clean the measuring cell windows (arrows)
from the outside with a clean, grease-free
cloth.

Insert the measuring cell back into the housing
and fasten in place with the locking screws.

If the desiccant is colored orange, then

the desiccant cartridge has to be replaced or
regenerated.
Ruby red = dry / orange = damp
