The Threshold setup register in the Transient module defines what voltage disturbance
magnitude should be considered as transient activity. Threshold is interpreted as a percentage of
the nominal system voltage, plus 100. For example, if you want transients recorded when voltage
deviates from nominal by 20%, enter 120 into the Threshold setup register.
For more information, see "Transients" on page 198.

Alarm event priorities
Your meter’s alarm priorities correspond to event priority ranges.
Alarm priority Event priority
High (red) 192–255
Medium (yellow) 128–191
Low (blue) 64–127
Info Only (no alarm)* 1–63
None (no alarm or event)* 0
*Alarms with priority of Info Only or None are not indicated or displayed.
Info Only and None event priority
Alarms with a priority of Info Only or None are not shown on the meter’s display, and do not
function as alarms. If the alarm’s priority is set to Info Only, and the event priority is greater than
the event log cutoff value, the associated event is recorded in the meter’s event log. If the alarm’s
priority is set to None, the event priority is automatically set to zero, and no associated event is
logged in the meter’s event log.
For events that you want to log for future reference or troubleshooting, but don’t want alarm
functions, set the alarm priority to Info Only.
For nuisance events that frequently occur, and you have no desire to log for reference or
troubleshooting, set the alarm priority to None.
Alarm indicators
Your meter’s display has an alarm indicator to show you what alarm levels have been detected
(active or historic) and whether they have been acknowledged.
For active high priority alarms, the display will also flash until the alarm is acknowledged. There is
also an alarm LED to indicate the meter’s alarm condition.
