Current clamp factor

When a current clamp sensor or transformer is connected to the system multimeter (V or
mA/A input) all current displays appear with the correct value in accordance with the selected
transformation ratio.

Voltage level

Voltage level measurement is used in order to
ascertain overall attenuation or boosting of a
transmission system.

Reference level

Reference value for alternating voltage level measurement (see dB).

dEMAnd tiME

Time interval for mean
value generation

This parameter specifies the observation time period for mean value generation during power
measurement (see page 50). Acquisition is synchronous to clock time, for which reason the first
mean value usually does not span the entire specified duration.
