Test results:
MAN x ½: If the RCD does not trip, the instrument beeps twice
indicating a successful outcome. (see screen on unit)
MAN x1, x2, x5: If the RCD trips within limits, the instrument beeps twice
suggesting a successful outcome. (see screen on unit).
Please note that the internal values apply for RCDs
manufactured to comply with BSEN61008. RCDs which are
manufactured to comply with BS4293 are required to operate in
0.2s at 1X I

. It is important that the user of this instrument is
aware of the applicable tripping time(s) for the RCD being
tested.
Please refer to the full user manual for tripping times.
AUTO: The instrument carries out the following 6 tests with different
values of rated current.
½ x I
Δ
n @ 0° - The RCD should not trip
½ x I
Δ
n @ 180° - The RCD should not trip
1 x I
Δ
n @ 0° - The RCD trips (blinking RCD) - Switch RCD on again
1 x I Δ n @ 180° - The RCD trips (blinking RCD) - Switch RCD on again
5 x I Δ n @ 0° - The RCD trips (blinking RCD) - Switch RCD on again
5 x I

RAMP: The instrument generates a leakage current growing step by
step in a given time interval. At the end of the test, if the RCD
tripping current is < I
Δ
n (type AC) or 1.4xI
Δ
n ( type A with
I Δ n>10mA ) the instrument beeps twice indicating a positive
outcome of the test.
If the parameters set on the instrument are consistent with the
RCD under test, the ramp test will cause RCD tripping with a
current lower than or equal to the selected rated differential
current.
