The instrument doesn't
detect an efficient
protection circuit.
FUNC
IdN RCD UL
Using the R
A
function,
if a contact voltage
U
t
higher than the
selected limit (U
L
) is
detected the instrument
emits
a long sound
signal at the end of the
test and displays the
screen alongside.
The test can be stored pressing the
SAVE key twice (according to paragraph 9.1).

If the RCD trips during

performed before the
test (independently from
the working mode) the
instrument displays the

FUNC
IdN RCD UL
The RCD trips too early.
Check if the RCD Nominal
Current is correct.
Some leakage currents
may be present in the
installation. Disconnect all
the loads connected
downstream the RCD.
THE PREVIOUS RESULTS CAN'T BE SAVED.

FUNC
IdN RCD UL
In the tests MAN x1, x2,
x5 and AUTO (during x1
and x5 tests), if the RCD
trips to separate the
circuit within a time not
complying with the limits
reported in Table 3, the
instrument emits
a long
acoustic signal at the
end of the test and
displays the values
alongside.
The test can be stored pressing the
SAVE key twice (according to paragraph 9.1).
