no event end time,
extreme value is only for the period until the stop of recording,
average value is not given,
only the beginning waveform is available for RMS voltage or current related events.
In order to eliminate repeated event detection when the parameter value oscillates around the
threshold value, the analyzer has a functionality of user-defined event detection hysteresis. It is
defined in percent in the following manner:
for RMS voltage events, it is the percent of the nominal voltage range (for example 2% of 230 V,
that is 4.6 V),
for RMS current events, it is the percent of the nominal current range (for example for C-4
clamps and absence of transducers, the 2% hysteresis equals 0.02×1000 A = 20 A),
for remaining parameters, the hysteresis is specified as a percent of maximum threshold (for
example, if the maximum threshold for current crest factor has been set to 4.0, the hysteresis
will be 0.02×4.0 = 0.08.
