If in a 230V system, the
instrument detects that
terminals B3 and B4
have been exchanged,
the following message
appears on the display.
Check the connection of
the separate cables.

If the instrument detects
that, in case test is
carried out, a Contact
Voltage higher than the
limit value set would be
found in the system
being tested, it does not
perform the test and the
following message
appears on the display.
Check for the efficiency
of the PE conductor and
of the grounding system.

If the instrument detects
an Earth resistance so

grounding system itself
may be considered
missing, the following

the display. Check for
the efficiency of the PE
conductor and of the
grounding system.
