sure a capacitive coupling to earth.
- Apply the probe tips L1/-
conductors (phases) and check whether the external con-
ductor voltage of e.g. 400 V is applied.
- A clockwise phase sequence (phase L1 before phase L2)
is given, if the green LED „►" of the phase sequence in-
dication
indication
- A counter-clockwise phase sequence (phase L2 before
phase L1) is given, if the green LED „◄" of the phase
sequence indication
sequence indication
- The phase sequence test always requires a countercheck
with the probe tips L1/-
ing which the phase sequence must change.
Note:
The phase sequence test can be carried out in an earthed
three-phase mains from 400 V - 900 V, 50/60 Hz (phase to
phase) on. Protective clothing and insulating conditions on site
might impair the function.
8. Continuity test (figure I)
- The continuity test must be carried out on system parts
which are free of voltage. If necessary, capacitors have to
be discharged.
- Apply the two probe tips L1/-
parts to be tested.
- In case of continuity (R < 100 kΩ), an acoustic signal is
emitted and the yellow LED Ω
- If a voltage is applied to the test point, the voltage tester
automatically switches over to the voltage test function
and indicates this function.
9. Resistance measurement (figure J)
- The resistance measurement must be carried out on sys-
tem parts which are free of voltage. If necessary, capaci-
tors have to be discharged.
- Short-circuit the probe tips L1/-
the push-button
the kΩ symbol
6 . Display: „OL" stands for a measured value which is
outside the measuring range.
- The resistance measurement function is active for approx.
10 seconds.
- Apply the probe tips L1/-
parts to be tested in order to measure resistances from
0.1 kΩ to 300 kΩ.
Note:
If required, it is possible to carry out a null balance with the
resistance measurement function being activated. For this pur-
pose, short-circuit the probe tips L1/-
and hold the push-button
approx. 2 seconds until „0.0" kΩ is shown on the LC display.
10. Diode test (figures K/L)
- The diode test must be carried out on system parts which
are free of voltage. If necessary, capacitors have to be dis-
charged.
- Short-circuit the probe tips L1/-
the push-button
the diode symbol
display
- The diode test is active for approx. 10 seconds.
- Apply the probe tip L1/-
tip L2/+
ducting-state voltage between 0.3 V and 2 V. In case of a
defective (broken down) diode, a voltage value of approx.
0.0 V will be displayed.
- In case of a diode tested in non-conducting direction, the
LC display shows „OL".
11. Cable break detector (figure M)
- The cable break detector is intended for the non-contact
localization of cable breaks on exposed live lines.
- Switch the voltage tester on by briefly actuating the push-
button 7
on for approx. 10 seconds!). When the device is switched
on, the display shows „0.0".
- Fully grasp the display handle L2
tor 5 over a live line (e.g. a cable reel or a chain of lights)
from the feeding point (phase) in direction of the other end
of the line.
- As long as the line is not interrupted, the yellow LED Ω
for continuity is flashing.
- The point of the cable break has been localized as soon as
the yellow LED Ω
Note:
The cable break detector may grounded power from 230 V,
50/60 Hz (phase to earth) are used. Insulating protective cloth-
ing and site conditions can affect the function.
12. Measuring point/display illumination (figure N)
- The measuring point illumination

- The off automatically after 10 seconds
- The background lighting of the LC display
automatically by means of a light sensor
13. Battery replacement (figure O)
- Do not apply voltage to the device when the battery com-
partment is open!
- Please replace the batteries as soon as the
is shown on the LC display
- The battery compartment is located on the back of the dis-
play handle L2/+
- Unscrew the screw of the battery compartment cover and
replace the used batteries by two new micro batteries
(LR03/AAA).
