Once a parameter is selected, a threshold window will open allowing you to set
the trigger value.
Duration: The alarm will only be recorded if the duration of the parameter meeting
the threshold criteria exceeds the duration. The minimum alarm duration can be
in minutes or seconds. In the case of Vrms or Arms not using neutral current, can
also be in hundredths of a second.
For Vrms and Arms, it can be useful to set a duration of 0 seconds. In that case
an event as short as a half cycle can be detected (8 milliseconds at 60Hz). For all
other parameters, the minimum duration that can be detected is 1 second.
NOTE: It is possible to check for alarms, records and search for transients at the
same time.
