12. MENU AND VARIABLES
12.1 - 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
IB = 0 – 65535 A RMS value of Phase B current
IC = 0 – 65535 A RMS value of Phase C current
Io = 0.0 – 6553.5 A RMS value of Zero Sequence Current (RMS Primary Amps)
Tem = 0 - 65535 %T Actual temperature rise
12.2 - Measure (Instantaneous Measurements)
Real time measurements can be frozen at any moment selecting the menu “Instant Measure” :
“ R eal T ime M eas”
“Measure”
“1 st Measurement
other measurements
to go back to “ Measure”
