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!
The voltage tester is marked with international
electric symbols and symbols for indication and
operation with the following meaning:

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
