9.1.2 Fault Diagnosis with WARNING Messages

The M200A monitors several internal values for alarm conditions. If the condition for an alarm
is met, the alarm is displayed on the front panel and the warning is transmitted out the RS-232
port. If a warning is present, it can be cleared by pressing the CLR key on the front panel. If
uncleared warnings are present they can be examined by pressing the MSG button on the
keyboard. Any time the instrument is powered up the SYSTEM RESET alarm will be displayed.
Generally, it is ok to ignore warnings that are displayed shortly after power-up, only if they
persist should they be investigated.
Table 9-2 shows the warning messages and gives some possible causes.
