Electrical specifications

Note: The measuring precision is specified as the sum of
- a relative fraction of the measured value and
- a number of digits (counting steps of the least significant digit).
This specified measuring precision is valid for temperatures in the range from 23 °C ± 5 °C and
relative humidity less than 80 %.
7.1 DC voltage range
The input resistance is ≥ 1 MΩ.
Measuring range
50.00 V
300.0 V
7.2 AC voltage 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 the final measuring range value
Crest factor < 4.0 up to 50 % of the final measuring range value
The input resistance is ≥ 1 MΩ.
