12. Menu and Variables
12.1 - Misure in Tempo Reale ( Real Time Measurements )
Scrolling display of the Real Time Measurements is the Default operation.
Scrolling can be stopped at any of the measurements and restarted by pressing the Reset button .
When stopped on one variable, appears aside the measurement and the different available measurements
can be selected by the buttons.
Display Description
I = 0 – 65535 %In Largest of the 3 phase-currents (% of rated current)
IA
= 0 – 65535
A
RMS value of Phase A current (Primary Amps)
IB = 0 – 65535 A RMS value of Phase B current (Primary Amps)
IC = 0 – 65535 A RMS value of Phase C current (Primary Amps)
Io = 0.0 – 6553.5 A RMS value of Zero Sequence Current (Primary Amps)
Vo
= 0 – 65535
V
Zero sequence voltage
alfa0 = 0 – 360 ° Displacement angle Io-Vo
12.2 – Misure ( Instantaneous Measurements )
