Alternative option:
Check the outer conductor relative to the protec-
■
tive conductor.
3 If it is a phase conductor, the voltage present
should be indicated.
Note
Recall that in this test an additional
current flows along the protective
conductor. This is added to an already
existing current and could trip the
circuit breaker (RCD).
Rotary field check (> 200 V AC) (fig. I)
Note
Protective clothing and insulating loca-
tions can influence the function.
Grasp the full surface of the handle [4] below
■
the physical marking [2].
Hold test probes L1 [1] and L2 [5] against two
■
outer conductors (phases) and check whether
the outer conductor voltage of e.g. 400 V is
present.
3 A clockwise rotating field (i.e. phase L1 before
phase L2) is indicated if the letter "R" is output to
the display.
3 An anticlockwise rotating field (i.e. phase L2
before phase L1) is indicated if the letter "L" is
output to the display.
After a rotary field check, always repeat the check
with reversed test probes. This must cause the direc-
tion of rotation to change.
Note
The rotary field check can be
performed above 200 V, 50/60 Hz
(phase relative to phase) in the earthed
3-phase AC grid. The "third" phase
L3 is simulated using a sensor in the
device by fully gripping the handle.
Single-handed test (fig. I)
Lock the two handles [4] using the spacer on
■
the test lead.
Adjust the separation of the test probes by
■
rotating. (Schuko socket/CEE)
Test point light (fig. I)
To switch the test point light on or off, press and
■
hold the "L.H." button [7] for several seconds.
Continuity check (fig. I)
Place the test probes [1] and [5] against the
■
lead, fuse, etc. to be tested.
3 For resistances between 10 - 199.9 kΩ, the
resistance value is output to the display.
3 For resistances > 200 kΩ, the overflow indica-
tion "OL" is output to the display.
3 An audible signal is output below 5 kΩ.
Load switch on /FI/RCD trip test. PE
(protective conductor test) (fig. I)
To reduce interference voltages, and inductive
■
and capacitive coupling during voltage testing,
press both "FI/RCD" buttons [3] simultaneously.
3 A lower impedance is switched on.
3 The peak current is below 0.3 A (I
button is pressed.
3 The voltage is indicated.
3 The additional load circuit is overload protect-
ed and reduces the load current after a few
seconds.
This integral load makes it possible to trigger an
RCD circuit breaker. The FI/RCD (max. 30 mA,
230 V/AC) is tested between phase and PE
conductor.
Hold a test probe against one phase conductor.
■
Hold the other test probe against the protective
■
conductor.
Press both "FI/RCD" buttons in as far as pos-
■
sible.
3 If the circuit breaker is not tripped, the applied
voltage is indicated in the display.
3 If the circuit breaker is tripped, the voltage
indication goes out.
Note
Without both buttons being pressed the
circuit breaker is not normally tripped
under normal circumstances.
Note
Only perform an RCD test on fixed
installed systems and circuits. Testing
on moving and not permanently wired
devices, extension leads, etc. can, in
the event of a fault, result in a high
current in metallic parts connected to
the protective conductor.
Note
The RCD test does not replace
VDE 0100 compliant tests on RCD
circuit breakers.
