11. Control
The electrochemical sensors for gas analysis are subject to normal
wear and tear as they age. Their accuracy may decrease as time
goes on, depending on the gas concentration, the exposure time and
the soiling grade of the sampled gas. The analyzer monitors the sen-
sors and corrects drift.
If the drift and the correlated measurement errors increase, an error
message is displayed. In this case, the corresponding sensor must be
changed by an authorized service center. The control menu has in-
formation about the current status of the sensors.
Further information is can be seen on 3 display pages (use the arrow
