44..11.. VVoollttaaggeess
You can view the various AC voltages by pressing the
U/V
button successively. Their values are expressed in true root mean square Volts.
Depending 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
U/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

 Press
U/V
again to get the three phase-to-neutral voltages:
V1
= voltage across phase 1 and neutral
V2
= voltage across phase 2 and neutral
V3
= voltage across phase 3 and neutral
 Press
