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

L1 is equipped with a display

 . The test probe

 . 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 lightemitting 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 phasesequence 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 phasesequence 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  !

- 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 threephase 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.

- 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 countertest! 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 or in insulated locations.

 might be impaired due to unfavorable light conditions, protective clothing

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!
