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)!
- At operating sites with a high noise level, it has
to be checked before use if the test signal can be
perceived.
- The voltage tester must be used only within the
nominal voltage range of 12 V up to AC 690 V/ DC
750 V!
- Do not operate the voltage tester with the battery
compartment being open!
- 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
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 690 V/ DC 750 V), the voltage tester must
not be used for a duration of 240 seconds!

2. Functional description
The DUSPOL
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
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-
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
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
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 .
