Bandwidth : Sets the "monitoring window" for forms of monitoring: Band violation
and Constancy . In Band monitoring/violation , the "monitoring window" is sym-
metrical to the threshold. The value entered acts as a subtraction to the window
with
band monitoring in positive and negative directions, and as an addition with
band violation .
Example: Threshold = 50, bandwidth = 3
→
means the range from 47 to 53 is
monitored.
Delay : The alarm condition must be me during the specified time to trigger an
alarm. The option is an alternative to the Hysteresis option and is especially suit-
able for suppressing false alarms for brief signal distortions with high amplitudes.
Both options can be combined.
Latching : The alarm is latched (continues to alarm) even when the alarm condition
is no longer met. Enabling Latching changes the field label in Reset trigger for
latching. The alarm resets when a reset event occurs, e.g. a rising edge in the
given channel. The Reset priority option causes an alarm to reset when the alarm
condition is still met.
