General Description
Description Specifically for this Instrument
A scaling factor (capacitive linear electric constant) must be entered in order to be able to
measure cable length in meters or kilometers.
Relationship of peak value to TRMS value.
Measuring range: 1.0  CF  11.0
When a current clamp sensor or transformer is connected to the system multimeter (V
mA/A input) all current displays appear with the correct value in accordance with the selected
transformation ratio.
Voltage level measurement is used in order to
ascertain overall attenuation or boosting of a
transmission system.
Where U = U = dbrEF (reference level).
1 REF
Display value > 0 dB: boosting; display value < 0 dB: attenuation
Parameter: dbrEF
Reference value for alternating voltage level measurement (see dB).
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.
If the TRMS half-wave value falls short of the specified diP LiMit value, a voltage drop (dip) is
detected. Parameter: diP LiMit
Unit of measure in digits, 60,000 = full measuring range
Descriptions of device parameters and their settings (which are
not listed here) are included in section 6.
