4.1. V V oltages
You can view the various AC voltages by pressing the V button successively. Their values are expressed in true root mean square Volts. Depen-
ding on the client's needs (type of electrical installation), several screens are possible:
! 3 phase with neutral (3ph+N)
! 3 phase without neutral (3ph)
! 2 phase (2ph+N)
! 1 phase (1ph+N)
Note: one of the four choices above has been factory programmed as per the client's specification.

! Press V to get the three phase-to-phase voltages:
U12 = voltage across phase 1 and phase 2
U23 = voltage across phase 2 and phase 3
U31 = voltage across phase 3 and phase 1

V1 = voltage across phase 1 and neutral
V2 = voltage across phase 2 and neutral
