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.

7.6 Diode and continuity test

The stated measuring accuracy is applies to a range between 0.4 V and 0.8 V.
Overload protection for diode tests: 600 V
The built-in buzzer sounds in the case of a resistance R less than 250 Ω up
to 850 Ω. For a resistance R higher than 850 Ω, the buzzer does not emit an
acoustic signal.
