Harmonics Average Histogram (Avg Bar)
During active GENERAL RECORDER, Harmonics average histogram AVG view is available (see section 3.14
for instructions how to start GENERAL RECORDER). In this view average voltage and current harmonic
values are shown (averaged from beginning of the recording to the current moment). Harmonics
average histogram screen displays dual bar graphs. The upper bar graph shows average voltage
harmonics and the lower bar graph shows average current harmonics.
