SYSTEM_DF1 [Record] TIME PLOT Interval (setting period)
Approx. 200 ms aggregation (50 Hz: 10 cycles, 60 Hz: 12 cycles)
Voltage RMS value is calculated for one
waveform shifted over half a wave.
Example:
There are 24 calculated U (Urms1/2) values
in an approx. 200 ms aggregation at 60 Hz
(12 cycles).

The result of adding the two waveforms
prior to and the two waveforms after the
approx. 200 ms aggregation is displayed
as the event waveform.
