Fault messages are references to certain changes in the analyzer
which influence its ability to measure correctly.
If the analyzer is in measuring mode, the occurrence of a fault is
indicated by an "F" at the right edge of the display.
Fault messages are logged and can be called in input mode using the
menu path "Analyzer status - Status - Logbook/faults" (see Section
5.7.1.1). The corresponding message texts are stored as alphanumeric
text in the logbook. You can delete the messages by pressing the
ENTER key. However, they appear again if the cause has not been
eliminated.
Table 6-1 provides a summary of fault messages, their causes, and
measures to eliminate the faults. If a remedy is not listed, you must
contact the servicing department when this fault message occurs.
