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
18 °C to 28 °C and relative humidity less than 80 %. The stated accuracy is
specified for 1 % to 100 % of the final measuring range value.
Additional specifications for AC functions:
The measuring value is gained and indicated as effective value (True RMS, AC
coupling). In case of non-sinusoidal curves, the indicating value becomes inaccu-
rate. Thus, an additional error occurs for the following crest factors:
crest factor from 1.0 to 2.0 additional error + 3.0 %
crest factor from 2.0 to 2.5 additional error + 5.0 %
crest factor from 2.5 to 3.0 additional error + 7.0 %
Maximum crest factor of the measuring signal:
crest faktor 3.0 @ 3000 digits
crest faktor 2.0 @ 4500 digits
crest faktor 1.5 @ 6000 digits
Measured values < 20 digits are set to 0 on the digital display K .
Square-wave signals are not specified.
