3.8.1 Settings of measurements
Select item RCD I
A
or RCD t
A
.
Define the displayed measure-
ment components with the
icon:
if RCD I
A
has been selected,
if RCD t
A
has been select-
ed.
For RCD I
A
the following pa-
rameters are available:
I
A
– RCD tripping current,
U
B
– voltage measured on PE,
R
E
– PE continuity,
t
Ai
– RCD triggering time when
measuring tripping current.
For RCD t
A
the following pa-
rameters are available:
U
B
– voltage measured on PE,
R
E
– PE continuity,
t
A
– RCD triggering time when
given the rated differential cur-
rent ratio.
