The measured value is obtained by mean value rectification and is displayed
as r.m.s. value.

The measuring accuracy is specified for a sinusoidal curve. In case of non
sinusoidal curves, the accuracy of the displayed value decreases. thus, an
additional error results for the following crest factors:
Crest factor from 1.4 to 3.0 additional error ± 1.5 %
Crest factor from 3.0 to 4.0 additional error ± 3 %

The maximum permissible operating time is limited from current value ≥ 7 A.
