Monitoring measurements
To access the primary current values by activating the monitoring state:
1. Press
and
simultaneously to view the primary line currents on phases I
a
, I
b
and I
c
and the ground-fault current, I
n
.
2. Press
to return the display to the idle mode.
The display has to be in the idle mode to be able to activate the monitoring state.
The display is not returned to the idle mode automatically as the monitoring state
does not have a time out. In case a fault is detected, however, the fault target
displaces the monitoring state.
