Electrical data

Note: The measurement accuracy is stated as the sum of
- a relative proportion of the measurement value and
- a number of digits (i.e. numerical steps of the last place).
This measurement accuracy applies for a temperature of 18 °C to 28 °C and a
maximum relative humidity of max. 80 %.
The measurement value is obtained as a true RMS value (AC coupling) and
displayed as such. Square-wave signals (> 100 Hz) are not specified. With
non-sinusoidal curves, the value displayed is less accurate. This results in an
additional error for the following crest factors:
Crest factor of 1.0 to 2.0, additional error + 1.0 %.
Crest factor of 2.0 to 2.5, additional error + 2.5 %.
Crest factor of 2.5 to 3.0, additional error + 4.0 % (applies to up to 4000 digits).
