Alarms Menu
Alarm Settings opens a window where various alarms can be set. Alarms will only be active if
Enable Alarms is checked. Alarms can be set for any ROI in the currently loaded ROI Set or
for the overall spectrum. Alarms can be set for either a gross count rate or for an increase in
gross count rate over a specified period of time. Any two alarms can also be attached to the
logical alarm outputs on the Mini DIN-7 connector. The outputs go “high” (+5V) in an alarm
condition.
Show Alarm Window opens the same window that is automatically opened when any alarm
condition occurs.
