2. Functional description
The DUSPOL
®
digital plus is a two-pole voltage
tester according to IEC 61243-3 with digital display.
As supplementary function, the voltage tester is
equipped with a measuring point illumination and
display illumination as well as with a phase and
phase-sequence indication. For all these functions,
the voltage tester requires a built-in battery (2x micro
LR03/ AAA). Determining the phase of external
conductors and the phase-sequence of a three-phase
mains is only possible provided the neutral is earthed.
The voltage tester is designed for DC and AC voltage
tests within the voltage range of 5 V up to AC 500 V/
1.5 up to DC 750 V. It can be used to perform polarity
tests at DC voltage.
The voltage tester consists of the test probes L1
and L2 and a connecting cable
. The test probe
L1 is equipped with a LC display
. Both test
probes are provided with push buttons
. From a
voltage of 6 V onwards, the voltage tester switches on
automatically. For voltage tests below 6 V, the voltage
tester has to be switched on by briefly pressing the
push button
of test probe L2 . The voltage tester
only works properly with the batteries (inside test probe
L1 ) being intact and inserted correctly. The display
indicates voltages within the nominal voltage range
of 5 V up to AC 500 V/ 1.5 up to DC 750 V. Exceeding
the limiting value for low voltages (ELV, AC 50 V, DC
120 V) is additionally indicated on the display.
By pressing both push buttons, the voltage tester
switches to a lower internal resistance (suppression
of inductive and capacitive voltages). 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 means of the push button
of test probe L1
with the device being switched on. Depending on
the brightness, the LCD background illumination is
activated automatically.
Hold Function
If you press and hold the push button
of test probe
L1 during a voltage test, the last measuring value
is indicated and is flashing. The voltage tester can be
separated from the unit under test and the measuring
value can be read (DATA-HOLD). The value can be
deleted by releasing the push button.
Display field
The display field
consist of an LC display. This
display indicates the exceeding of the upper limiting
value for low voltages (ELV)
, the phase, the
phase-sequence
and
, the exact voltage value
, the polarity at DC voltage
and
as well as a
symbol for weak batteries
. The measuring range for
continuous voltage measurement is set automatically.
Up to 80 V, the value is indicated with a decimal place.
For higher values, the decimal place is not indicated.
3. Functional check

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 1.5 V up to DC 750 V!
- Never connect the voltage tester to voltage for
longer than 30 seconds (maximum permissible
operating time = 30 s)!

or a – symbol
. Here,
the indicated pole is the pole measures by the
indicating handle .
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 voltage tester must be used only within the
nominal voltage range of 5 V up to AC 500 V!
- The phase-sequence test is possible from 230 V
AC voltage (phase against phase) onwards in a
earthed three-phase mains.

- The three-digit display has to indicate the voltage
of the external conductor.
- 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
symbol “ “ (phase-sequence clockwise)
. If for
two phases the rotation is counter-clockwise, the LC
display indicates the symbol “
“ (phase-sequence
counter-clockwise)
.
The phase-sequence test always requires a counter-
test! For this purpose, the measurement has to be
performed again with reversed contact electrodes
.
During the counter-test, the LC display must indicate
the opposite phase-sequence. If in both cases, the
LC display indicates a clockwise phase-sequence, the
earthing is too weak!
Note:
The reading of the LC display
might be impaired
due to unfavorable light conditions, protective clothing
or in insulated locations.
7. Battery replacement
Do not set the voltage tester under voltage with the
battery compartment being open!
The energy supply of the DUSPOL
®
digital plus is
done by means of two built-in micro batteries (LR03/
AAA). Battery replacement is necessary as soon as the
display shows the battery symbol “
“ (weak battery)
. The symbol appears in case the battery voltage is
below 2.75 V. If the battery voltage drops below a value
of approx. 2.5 V, the battery symbol is flashing.
Indicating the battery voltage
Switch the voltage tester on by briefly pressing the
push button
of test probe L2 . After approx. 10
seconds, the value of the battery voltage is indicated
for 1 second. (Example:
)
How to replace the batteries:
Take a screw driver and open the battery compartment
(next to the cable outlet) by a 1⁄4-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 1⁄4-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!
8. 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
number 772871. Moisten a new O ring with vaseline or
talcum so that the battery compartment can be locked
and unlocked easily.
