or
Press the
START key once to execute a test with 180° Current waveform.
CAUTION
Never disconnect the test leads when the message
"MEASURING" is
displayed.
RCD 05.06.01
The symbol
">" means that
the RCD did not trip.
Value of contact voltage
U
t
detected referred to the
rated value of the RCD
current set.
If the RCD
does NOT
trip the instrument emits
a
double sound signal
indicating the positive
outcome of the test and
displays the screen
alongside.
OK: RCD passed the test.
