11.3 Measurement
In the Measurement menu, configure:
·The transformers for current and voltage mea-
surement
·The recording of transients
·The recording of events
·The "Relevant Voltage"
·The mains frequency
·The flicker settings
·The temperature sensor
The device has:
·4 measurement channels for current measure-
ment (I1..I4)
·4 measurement channels for voltage measure-
ment (V1..V4 against Vref).
The measured voltages and currents for mea-
surement channels 1-4 must all be from the same
network.
Main measurement
The main measurement includes the measure-
ment channels 1-3. Use measurement channels
1-3 in three-phase systems.
Auxiliary input
Only measurement channel 4 belongs to the
auxiliary input. Use measurement channel 4 for
measurement in single-phase systems or in three-
phase systems with a symmetrical load.
The settings for the frequency and the "Relevant
voltage" are taken automatically from the settings
for the main measurement.
