5. Press the GO/STOP key on the instrument or the START key on the remote switch
probe. The instrument will start the automatic test sequence.
CAUTION
If message “ Measuring… ” appears on the display, the instrument is
performing measurement. During this whole stage, do not disconnect the
test leads of the instrument from the mains.

7. The RCD test starts and the screen to the side appears
on the display. The trip-out current and the trip-out time
values appear on the display.
In case of a
positive result of all the tests sequentially
performed during the RCD test ( Trcd and Ircd
parameters) (see § 12.4), the instrument goes on with the
test on insulation resistance between L-N, L-PE and N-
PE conductors.
