Setpoint
Delta Alarm Setpoint is the change of the electric field magnitude required to trigger a Delta Alarm.
For example, with a setpoint of 1 kV/m the Delta Alarm will activate if the field increases or
decreases by 1 kV/m or more within the set interval time.
Interval
Delta Alarm Interval is the time frame that the electric field level needs to change in order to trigger
the Delta Alarm. For example, with an interval of 60 seconds, and a setpoint of 1kV/m, the field
level needs to increase or decrease by 1kV/m or more within 60 seconds to active the Delta Alarm.
Delay
The Delta Alarm Delay is the length of time the field difference must remain higher than the setpoint
before the alarm is activated. If the electric field difference drops below the setpoint before the delay
expires the delay timer will be reset. For example, with a delay of 30 seconds and setpoint of 1 kV/m
the electric field difference must remain above 1 kV/m or below -1 kV/m for 30 seconds before the
alarm activates.
Duration
Delta Alarm Duration is the length of time the Delta Alarm will remain active once the Delta Alarm
is triggered.
