2. Functional description
The DUSPOL
®
expert is a two-pole voltage tester
according to IEC 61243-3 with visual display. As a
supplementary device, the voltage tester is equipped
with a phase indication, phase-sequence indication,
measuring point illumination and a continuity check
function. The supplementary functions – except the
phase indication – are supplied via two replaceable
micro batteries (LR 03/ AAA). The signalling of the
continuity check is done optically and acoustically.
The voltage tester is designed for DC and AC voltage
tests within the voltage range of 12 V up to AC 690 V/
DC 750 V. It can be used to perform polarity tests in DC
and phase tests in AC. The voltage tester indicates the
phase-sequence provided that the neutral is earthed.
The voltage tester consists of the test probes L1
and L2 and a connecting cable
. The test probe
L1 is equipped with a display
. Both test probes
are provided with push buttons
. Without pressing
both push buttons, the following voltage steps (AC
or DC) can be indicated: 24 V+; 24 V-; 50 V; 120 V;
230 V; 400 V; AC 690 V/ DC 750 V. By pressing both
push buttons, the voltage tester switches to a lower
internal resistance (suppression of inductive and
capacitive voltages). Thus, also the indication of 12 V+
and 12 V- is activated. Furthermore, a vibrating motor
(motor with a flyweight) is put under voltage. From
approximately 200 V this motor is set in rotation. With
the voltage increasing, the motor’s speed and vibration
increases as well so that additionally by means of the
handle of test probe L2 the voltage value can be
estimated roughly (e.g. 230/ 400 V). The duration of
the test with a lower internal resistance of the device
(load test) depends on the value of the voltage to
be measured. To prevent excessive warming of the
voltage tester, it is equipped with a thermal protection
(reverse control). With this reverse control, the speed
of the vibrating motor decreases as well.
The measuring point illumination can be activated
by pressing the push button
of test probe L1 .
For the voltage measurement with ripple (two-pole
measurement), the illumination is activated with
reduced brightness. The activation of the continuity
check can be introduced by bringing together the two
contact electrodes
.
Display field
The display system consists of high-contrast light-
emitting diodes (LED)
indicating DC and AC
voltages in steps of 12; 24; 50; 120; 230; 400; AC
690 V/ DC 750 V. The indicated voltages are nominal
voltages. With DC voltage, the LEDs also indicate the
polarity for 12 V and 24 V (see chapter 5). The 12 V
LED can only be activated by pressing both push
buttons.
LC display
The LC display
serves for the phase test with
alternating current (AC) and indicates the phase-
sequence of a three-phase mains.
3. Functional check
- The voltage tester must be used only within
the nominal voltage range of 12 V up to
AC 690 V/ DC 750 V!
- Never connect the voltage tester to voltage for
longer than 30 seconds (maximum permissible
operating time = 30 s)!
- Check the voltage tester for correct function
immediately before use!
- Test all functions by means of known voltage
sources.
• For DC voltage tests use e.g. a car battery.
• For AC voltage tests use e.g. a 230 V socket.
• Connect both contact electrodes
to test the
continuity check for correct function.
• Check the battery status for the phase-
sequence indication by activating the
measuring point illumination. Replace the
batteries, if necessary.
Do not use the voltage tester unless all functions are
operating correctly!
Check the function of the LC display
by single-pole
connection of the contact electrode
of the test probe
L1 to an external conductor (phase).
4. How to test AC voltages
- The voltage tester must be used only within the
nominal voltage range of 12 V up to AC 690 V!
- Never connect the voltage tester to voltage for
longer than 30 seconds (maximum permissible
operating time = 30 s)!
- Firmly grasp the insulated handles and of
the 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 and L2
only! Do not cover the display and do not touch the
contact electrodes
!
4.1 How to test the phase at AC voltage
- The voltage tester must be used only within the
nominal voltage range of 12 V up to AC 690 V!
- The phase test is possible in the earthed mains
from 230 V onwards!
- Firmly grasp the handle of test probe L1 .
- Place the contact electrode
of test probe L1
against the relevant point of the unit under test.
- Never connect the voltage tester to voltage for
longer than 30 seconds (maximum permissible
operating time = 30 s)!
- If the “R” symbol appears on the LC display
,
the tester is in contact with the live phase of an
AC voltage on this point of the unit under test.
Never touch the contact electrode of test probe L2
during the single-pole test (phase test)!
Note:
The reading of the LC display
might be impaired
due to unfavorable light conditions, protective clothing
or in insulated locations.
Attention:
The absence of voltage can be detected by means of
a bipolar test only.
5. 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 and of
the 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 and L2
only! 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 and of
the 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 and L2
only! 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 and of
the 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
clockwise 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 is possible within the range of
0 - 108 kΩ.
- Firmly grasp the handles L1 and L2 .
- Place the test probes L1 and L2 with the
contact electrodes
against the relevant points
of the unit under test.
- When contacting an electrically conductive
connection with the contact electrodes
, the
voltage tester gives an acoustic signal and the
signaling LED
lights up.
8. Battery replacement
Do not set the voltage tester under voltage with the
battery compartment being open!
The energy supply for the phase-sequence indication,
illumination and continuity check of the DUSPOL
®
expert is done by means of two built-in micro batteries
(LR03/ AAA). Battery replacement is necessary as
soon as illumination does not work anymore. In this
case, the battery voltage is below 2.2 V.
How to replace the batteries:
Take a screw driver and open the battery
compartment (next to the cable outlet) by a
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. 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!

a longer period of time!
10. General maintenance:
Clean the exterior of the housing with a clean dry
cloth (exception: special cleansing cloths). Do not use
solvents and/ or abrasives to clean the voltage tester.
Make sure not to contaminate the battery compartment
and the battery contacts with leaking battery
electrolyte. Should such electrolyte contamination or
white deposits occur near the battery or the battery
housing, these must also be removed with a dry cloth.
In case of wear or damaging of the O ring of the
battery compartment, the voltage tester does not
comply with the indicated protection class anymore
(protection against dust and water). In this case, the O
ring must be replaced.
The O ring can be ordered under the BENNING piece
