Alarm limits
The 34970A/34972A has four alarm outputs which you can configure to alert you
when a reading exceeds specified limits on a channel during a scan. You can
assign a high limit, a low limit, or both to any configured channel in the scan list.
You can assign multiple channels to any of the four available alarms (numbered 1
through 4). For example, you can configure the instrument to generate an alarm
on Alarm 1 when a limit is exceeded on any of channels 103, 205, or 320.
You can also assign alarms to channels on the multifunction module. For example,
you can generate an alarm when a specific bit pattern or bit pattern change is
detected on a digital input channel or when a specific count is reached on a
totalizer channel. With the multifunction module, the channels do not have to be
part of the scan list to generate an alarm.
