1. Safety instructions:
- Hold the voltage tester only by the insulated
handles and and do not touch the contact
electrodes (probe tips)
!
- Immediately before use: Check the voltage
tester for correct operation! (see chapter 3). The
voltage tester must not be used if one or several
display functions fail or if the voltage tester is not
ready to operate (IEC 61243-3)!
- The voltage tester (voltage class A) must be used
only within the nominal voltage range of 12 V up
to AC 400 V/ DC 750 V!
- The voltage tester complies with protection class
IP 64 and therefore can also be used under wet
conditions (designed for outdoor use).
- For testing, firmly grasp the voltage tester by the
handles and .
- Never connect the voltage tester to voltage for
longer than 30 seconds (maximum permissible
operating time = 30 s)!
- The voltage tester only operates correctly
within the temperature range of -10 °C up to
+55 °C at relative air humidity of 20 % up to
96 %.
- Do not dismantle the voltage tester!
- Please protect the housing of the voltage tester
against contamination and damages!
- Please store the voltage tester under dry
conditions.
- To prevent injuries and discharge of the battery,
provide the contact electrodes (probe tips)
with the enclosed cover after using the voltage
tester!
Attention:
After maximum load (i.e. after a measurement of 30
seconds at AC 400 V/ DC 750 V), the voltage tester
must not be used for a duration of 240 seconds!

2. Functional description
The DUSPOL
®
combi 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 continuity check function. For this function,
the voltage tester has two built-in solar cells. The
signaling of the continuity check is done optically
by means of a LC display. The voltage tester is
designed for DC and AC voltage tests within the
voltage range of 12 V up to AC 400 V/DC 750 V.
It can be used to perform polarity tests in DC and
phase tests in AC. 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; 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.
Display field
The display system consists of high-contrast light-
emitting diodes (LED)
indicating DC and AC voltages
in steps of 12 V; 24 V; 50 V; 120 V; 230 V; 400 V; 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.
The two solar cells are top left and bottom right of
the display field. These cells generate the auxiliary
voltage necessary for the continuity check.
LC display
The LC display
serves for the phase test with
alternating current (AC) and indicates the successful
continuity check.
3. Functional check
- The voltage tester must be used only within
the nominal voltage range of 12 V up to
AC 400 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 the two test electrodes
to test the
continuity check function.
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 400 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 400 V!

- 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)!
Never touch the contact electrode of test probe L2
during the single-pole test (phase test)!
If the symbol ” ” appears on the LC display
, the
phase of an alternating voltage (AC) is at this point of
the unit under test.
Note:
The reading of the LC display
might be impaired
due to unfavorable light conditions, protective
clothing or in insulated locations.

.
Note:
