Influencing Quantities and Influence Error
1)
For temperature: specified error valid starting with temperature changes as of 10 K.
For frequency: specified error valid starting with display values as of 300 digits.
2)

Crestfaktor CF
Test signal: Rectangle 55 Hz, no DC component
The admissible crest factor CF of the alternating quantity to be
measured depends on the display value.
Crest factor 4 at the end of range, it is increased accordingly
when the range is reduced. However, due to input protection,
voltage is limited to 1000 V, therefore the admissible crest factor
in the 600 V ranges is half as high.
Power limiting: voltage x frequency max. 3 x 10
