Voltage Swell End Threshold
The swell end threshold is configured as a percentage of the reference voltage. A swell event ends
when the measured voltage value drops back below the end threshold. You can set a hysteresis value
between the start and the end thresholds to prevent multiple events from occurring during a short
period of time, and the minimum hysteresis value is 1 %. In other words, the end threshold can be set
to a value at least 1 % less than the start threshold. If the start threshold is set to a value less than the
end threshold, the end threshold is automatically reset to a value 1 % less than the start threshold.
