To view the various AC currents, press the A button successively. The values are expressed in true root mean square Amps. 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 A to get the three phase currents:
I1 = current in phase 1
I2 = current in phase 2
I3 = current in phase 3

! Press A again to get the neutral current:
In = current in the neutral
Note : the neutral current is calculated by vector summation of the three phase currents..
