The measured value of the BENNING MM 8 is obtained by a mean value recti-
fication and displayed as an effective value.
The measured value of the BENNING MM 9/ 10 is obtained as a real effective
value (TRUE RMS) and then displayed.
The measuring accuracy is specified for sinusoidal curves and is valid for
*1
indicating values below 4000 digits. For indicating values higher than 4000
digits 0.6 % have to be added to the specified measuring accuracy. In case
of non-sinusoidal curves below 2000 digits, the indicating value becomes
inaccurate. Thus, an additional error occurs for the following crest factors:
crest factor from 1.4 to 3.0 additional error ± 1.5 %
valid for sinusoidal curves 50 Hz/ 60 Hz
