How to test DC voltages

- The voltage tester must be used only within the
nominal voltage range of 12 V up to DC 750 V!
- Never connect the voltage tester to voltage for longer
than 30 seconds (maximum permissible operating
time = 30 s)!
- Firmly grasp the insulated handles
test probes L1 and L2.
- Place the contact electrodes  of the test probes L1
and L2 against the relevant points of the unit
under test.
- For AC voltages from 24 V onwards and when
pressing both push buttons (load test) from 12 V
onwards, the LEDs "plus" and "minus"  and  light
up. Furthermore, all LEDs light until the step value of
the applied voltage is reached.
- When pressing both push buttons  and from an
applied voltage of approx. 200 V onwards, a vibrating
motor is put in rotation inside the test probe L2
With the voltage increasing, the speed of this motor
is increasing as well.
Please make sure that you touch the voltage tester at the
insulated handles of test probes L1
Do not cover the display and do not touch the contact
electrodes !

5.1 How to test the polarity at DC voltage

- The voltage tester must be used only within the
nominal voltage range of 12 V up to DC 750 V!
- Never connect the voltage tester to voltage for longer
than 30 seconds (maximum permissible operating
time = 30 s)!
- Firmly grasp the insulated handles
test probes L1 and L2.
- Place the contact electrodes  of the test probes L1
and L2 against the relevant points of the unit
under test.
- If LED  lights up, the "positive pole" of the unit
under test is at test probe
- If LED  lights up, the "negative pole" of the unit
under test is at test probe
Please make sure that you touch the voltage tester at the
insulated handles of test probes L1
Do not cover the display and do not touch the contact
electrodes !
6. How to test the phase sequence of a three-phase
mains
The required auxiliary voltage is provided by the power
supply (2 x 1.5 V batteries) integrated into test probe L1
. Check the functional status of the batteries before
measuring by activating the measuring point illumination.
- The voltage tester must be used only within the
nominal voltage range of 12 V up to AC 690 V!
- The phase-sequence test is possible from 230 V AC
voltage (phase against phase) onwards in a earthed
three-phase mains.
- Firmly grasp the insulated handles
test probes L1 and L2.
- Place the contact electrodes  of the test probes L1
and L2 against the relevant points of the unit
under test.
- The LEDs have to indicate the external conductor
voltage.
- Never connect the voltage tester to voltage for longer
than 30 seconds (maximum permissible operating
time = 30 s)!

- When contacting the two contact electrodes  with
two phases of a three-phase mains connected in
clockwise rotation, the LC display  indicates the
"R" symbol. If for two phases the rotation is anti-
clockwise, no symbol appears on the LC display.
The phase-sequence test always requires a counter-test!
If the LC display  indicates clockwise rotation for two
phases of a three-phase mains, those two phases must
be contacted again with reversed contact electrodes
 during the counter-test. There must be no symbol
indicated on the LC display during the counter-test. If in
both cases the LC display indicates the „R" symbol, the
earthing is too weak or the batteries are empty.
Attention!
In case of empty batteries, „R" indication for clock-
of the wise and anti-clockwise rotation!
Note:
The reading of the LC display  might be impaired due
to unfavorable light conditions, protective clothing or in
insulated locations.
7. How to test an electrically conductive connection
(continuity check)
- The continuity check must be performed on the
relevant points of a "dead" (not being under voltage)
unit under test. If necessary, the capacitors must be
discharged.
. - The necessary test voltage is supplied by means of
the power supply (2 x 1.5 V batteries) integrated in
the test probe L1
- The test
only! 0 - 108 kΩ.
- Firmly grasp the handles L1
- Place the test probes L1
contact electrodes  against the relevant points of
the unit under test.
- When
connection with the contact electrodes , the voltage
tester gives an acoustic signal and the signaling LED
 lights up.

Battery replacement

Do not set the voltage tester under voltage with the
battery compartment being open!
The energy supply for the phase-sequence indication, il-
lumination and continuity check of the DUSPOL
is done by means of two built-in micro batteries (LR03/
AAA). Battery replacement is necessary as soon as illu-
mination does not work anymore. In this case, the battery
voltage is below 2.2 V.
How to replace the batteries:
only! Take a
compartment
¼-turn in direction of the arrow (counter-clockwise). The
slot is now vertical and the battery compartment with the
batteries can be removed.
Remove the discharged batteries from the battery
compartment. Insert the new batteries with correct
polarity (see marking) into the battery compartment. Put
the battery compartment with the batteries back onto the
handle and lock it by ¼-turn in clockwise direction (slot
must be horizontal and the marking points are opposite!).
Make sure not to damage the O ring. If necessary, it has
to be replaced.
Battery disposal:
Do not dispose of batteries with the household garbage.
of the You as a consumer are legally obliged to return used
batteries. You can return used batteries to public
collection facilities in your community area or return them
to any retail outlet selling similar batteries. Avoid using
batteries containing dangerous substances!
