Note
The voltage sensor at channel CH2 denoted with dotted lines is only
required for transient measurements; for current, voltage power
measurements, no sensor is required at CH2.
Associated Device Software Settings:

Check the respective option.

If the option IL2 = -IL1 - IL3 is checked, the current IL2 is calculated. If this option is not
checked, the current IL2 is measured by means of a sensor at phase L2 (Instrument
channel CH6).
Note
The nominal voltage has to be entered as a phase-phase voltage in the
dialogue Nominal-Limit values (i.e. 400 V in a 230 V P-N-system).
