[1] Under 5 % of measuring range: +70 counts
[2] Under 5 % of measuring range : +150 counts
[3] Under 5 % of measuring range : +350 counts
[4] At 100.000 V the accuracy is ± (15% + 50)
Crest factor >2.5 - 3.0: +4.0% Type of measurement: True RMS,
AC-coupled, calibrated to the sine waveform. For non-sinussoidal
measuring signals the following measuring errors must be added:
Crest factor 1.4 - 2.0: +1.0%
Crest factor >2.0 - 2.5: +2.5%
AC+DC measurement accuracy: +1.0%
dB/dBm: ± 60 dBm

Under 45 Hz the display can move <50 counts
Type of measurement: True RMS, AC-coupled, calibrated to sinu-
soidal waveform. The deviation in non-sine shaped measurement
signals corresponds to the AC voltage.
