Note
The phase-phase voltages V delta rms is measured as:
• V delta rms L1 or A: between L1 or A and L2 or B
• V delta rms L2 or B: between L2 or B and L3 or C
• V delta rms L3 or C: between L3 or C and L1 or A

The parameters are available for each specific phase (L1 or A, L2 or B, L3 or C) and also
for neutral N if applicable, except the total parameters which are for the whole 3-phase
supply system.
For details about symbols and abbreviations refer to Appendix at the end of the manual.
The scaling of the individual curves can be set.
There are 3 scaling options as follows:
• According to measurement range: Scales according to the measurement range of
each individual measured variable.
