Notes:
In mains protected with an RCD switch, whose
nominal current is 10mA or 30mA, the switch may
be activated during a voltage measurement be-
tween L and PE. In order to avoid that connect the
tester between L and N and after approximately 5s
switch the probe over from N to PE.
2.3 RCD operation test
In order to check the operation of the RCD
switch, whose nominal current is 10mA or 30mA,
perform a voltage test directly between the L
phase and the PE protective conductor.
2.4 Single-pole phase testing
Notes:
During single-pole phase testing for the pur-
pose of identification of external conductors, under
certain circumstances the functioning of the tester
may be impaired (e.g. if insulated individual pro-
tective means are used or is the working station is
insulated).
Note!
Do not touch the measurement probe electrode
L1 during the phase testing.
