5.3 Faults Alarm
Any faults in the hardware that makes the analyzer unable to carry out measurements, result
in a "fault alarm". The measured value flashes, and then it is always necessary to take
corrective measures.
The faults listed in the following table lead to a fault alarm message in the logbook. These
can be individually deactivated by using function 88.
