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.
and of - 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
and L2 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
and of 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
and L2 to public collection facilities in your community area
or return them to any retail outlet selling similar
batteries. Avoid using batteries containing dangerous
substances!

Attention!
The phase-sequence indication, measuring point

if the batteries are empty!
Remove the batteries if not using the voltage tester for
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
number 772897. Moisten a new O ring with glyzerin or
talcum so that the battery compartment can be locked
and unlocked easily.
11. Environmental notice
At the end of the product's useful life, please
dispose of it at appropriate collection points
provided in your country.
