Sensors
The sensors get calibrated with the reference gas fresh air by each
switch-on procedure. The state of the sensors is permanently
controlled by the instrument. If an error message is displayed during
calibration and cannot be eliminated despite several calibration
phases, so the instrument must be checked by a qualified and
authorised service centre.

filter (only with electrochemical CO sensor)
In the tubing leading to the electrochemical CO sensor on the top of
the instrument there is a chemical filter for filtering SO

and NO

out
of the flue gas. The filter material is manganese-4-oxide granules
and should be changed once it has turned grey (colour change:
pink> brown> black> grey> white).
Probe and hose (only probe type SB)
Depending on the frequency of use, probe and hose should be
regularly cleaned in order to release particle deposits and to prevent
early wearing due to corrosion:
-Release the connections at the instrument and at the probe
grip to free the hose.
-Clean the hose (flow warm water in then dry respectively blow
water drops out).
Change printer paper roll
-Release the printer cover.
-If necessary, extract the paper rest out of the printer
