4. Press the START key once to execute the test. The instrument carries out the
following six tests with different values of rated current:
 1/2I
n
with 0° current waveform (the RCD shall not trip).
 1/2I
n
with 180° current waveform (the RCD shall not trip).
 I
n
with 0° current waveform (the RCD trips, message "RESUME RCD").
 I
n
with 180° current waveform (the RCD trips, message "RESUME RCD").
 5I
n
with 0° current waveform (the RCD trips, message "RESUME RCD").
 5I
n
with 180° current waveform (the RCD trips, end of the test).
The test is good if all values of tripping times are within the limits reported in
Table 3.
WARNING
Never disconnect the test leads from the circuit under test when the
message " MEASURING " is displayed.

At the end of the test if
all six tests resulted to
be positive, the
instrument displays the
screen alongside
relative to the last
measurement effected.
