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 and/or and the alarm sense as "HI" or "LO".
3-10
The limit sense is changed to "OFF". Alarm checking and the alarm limit values are
re-enabled by setting limit sense to "HI" or "LO".
An open thermocouple has been detected on that channel (thermocouple temperature
function only).
