Alarm Indications
Generally, the ALARM annunciator is dimly lit whenever the last measurement on any
channel was found to be in alarm. When the displayed channel is in alarm during review,
the ALARM annunciator flashes, LIMIT is lit, and additional annunciators show the
alarm limit as
S and/or T and the alarm sense as "HI" or "LO".
