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.
6. The Ra test starts and the screen to the side appears on
the display. After approx. 20s , the Ra ends and ithe
values of RA (overall earth resistance) and Ut (contact
voltage) immediately appear on the display.
In case of a
positive result of the Ra test (see § 12.8),
the instrument goes on with the test on the trip-out current
and trip-out time of the RCD.

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 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.

8. The insulation test starts and the screen to the side
appears on the display. The RL-N, RL-PE and RN-PE
values appear on the display.
In case of a
positive result of all the test sequentially
performed during insulation test (insulation resistance >
minimum limit threshold), the instrument has completed
its tasks, shows the “OK” message and displays the
screen to the side.
