Disturbance (sag/swell) alarms
The meter monitors system’s voltage for sags or swell events. It reports the disturbance magnitude and timestamp when the event occurs.
You must configure voltage level, sag limit, swell limit and hysteresis for these alarms to function.
Your meter has two disturbance alarms:
Disturbance alarm triggered due to sag events
Disturbance alarm triggered due to swell events
