In case the instrument is unable to
generate the current because the fault
loop presents a too high resistance, the
instrument emits
a long sound signal
at the end of the test and displays the
values alongside.

Message ">100V" or “>50V”:
the instrument detected a contact voltage higher
than the full scale. Under U
t
mode the instrument
full scale is equal to 100V or 50V depending on the
value set for U
L
equal to 50V or 25V.
Message “rcd”:
the RCD trips too
early. Some
leakage currents
may be present in
the installation.
Message “hot”: the instrument got overheated.
Message
“
HI rES”: the
instrument
detected a too
high resistance
therefore it is
unable to effect
the test.
