Meter Configuration
A triggered alarm will cause the Alarm Status indicator at the top of ViewPoint HD to turn red. If an
alarm is enabled but not triggered, the indicator will be bright green. If no alarms are enabled, the
indicator remains dark.
Host systems are notified of an alarm via a hardware circuit (normally low) that can be wired to an
interrupt input. Details about which alarm triggered are determined by reading the status registers
under the alarm block 2450 – 2500.
Alarms no longer need to be “cleared” by the host. The alarm will be expressed whenever the condition
exists and will clear itself if measured values exceed the trigger points. Alarm conditions are evaluated
by the meter once per second.
