4.3. RCD RCD : TESTS ON RCDS TYPE A OR AC
The test is effected according to IEC/EN61557-6, EN61008, EN61009, EN60947-2 B 4.2.4
and VDE 0413 part 6.
CAUTION
The automatic check of the RCD features causes the tripping of the RCD itself.
Therefore
check that there is no power or load connected downstream the
RCD under test which could be affected by the installation switching off.
Possibly disconnect all the loads connected downstream the RCD as they could
add other leakage currents to the existing ones so making the test results void.
Turn the switch on RCD (RCDS type A sensitive to pulsating
leakage current) or RCD (RCDS type AC sensitive to sine leakage
current) position.
Switch on the instrument.
The key
FUNC permits to select one of the following measuring modes
(which can be shown cyclically when pressing the key):
 Mode
MAN x ½ (the instrument effects the test with a leakage current
equal to half the value of the rated current set with a leakage current in
phase with the voltage or a leakage current phase shifted by 180° with
respect to the voltage).
 Mode MAN x 1 (the instrument effects the test with a leakage current
equal to once the value of the rated current set with a leakage current in
phase with the voltage or a leakage current phase shifted by 180° with
respect to the voltage).
 Mode MAN x 2 (the instrument effects the test with a leakage current
equal to twice the value of the rated current set with a leakage current in
phase with the voltage or a leakage current phase shifted by 180° with
respect to the voltage).
 Mode MAN x 5 (the instrument effects the test with a leakage current
equal to five times the value of the rated current set with a leakage
current in phase with the voltage or a leakage current phase shifted by
180° with respect to the voltage)
 Mode AUTO (the instrument effects the test automatically with a leakage
current equal to half, once, five times the value of the rated current set
with a leakage current in phase with the voltage or a leakage current
phase shifted by 180° with respect to the voltage). Recommended test.
 Mode RAMP (the instrument effects the test with a ramp growing
leakage current, with a leakage current in phase with the voltage or with
a leakage current phase shifted by 180° with respect to the voltage. Use
this test to measure the tripping current).
