7.3 AC current range
The measured value is obtained and displayed as real r.m.s. value (True RMS, AC coupling).
Its calibration is adapted to sinusoidal curves. In case of deviations from this curve shape, the
accuracy of the displayed value decreases.
Crest factor < 2.0 up to 100 % of each final measuring range value
Crest factor < 4.0 up to 50 % of each final measuring range value
