Benning's DUSPOL® Digital Voltage Tester

Digital True RMS voltage tester with resistance/frequency range a, for professional testing of DC and AC voltages, as well as phase and polarity testing with load connection.

Suitable for high-voltage systems in hybrid vehicle technology, electrical engineering, industry, maintenance, service (troubleshooting), photovoltaics/wind turbines

Tested and approved according to IEC/EN 61243-3 (DIN VDE 0682-401:2011-02), CAT IV 600 V resp. CAT III 1000V

Wire break detector (phase tester) for non-contact location of wire breaks in live and exposed cables - flashing yellow

Vibration alarm on test handle for reliable voltage detection

High impedance voltage test without pressing the button (direct indication)

Push button load connection (low resistance test)

Switchable load circuit, erroneous measurements due to reactive capacitive and inductive voltages are excluded by deliberate switching of the load via a push button

Intentional tripping of a 30 mA differential switch

Optical and acoustic continuity test by buzzer and yellow LED

Display of the direction of the rotating field with the direction of the arrow

Safe unipolar phase test

Illumination of the display and spot illumination of the measurement point by high-power white LED

Shock, dust and jet proof housing (robust with rubber grip surface)

Illumination of the LC screen activated automatically by the light sensor

Includes 2 1.5 volt micro batteries (LR03/AAA) (voltage display from 50 V even when batteries are flat)

*The workshop is not authorized to use a commercial multimeter, even if it is suitable for up to 1,000 V. But why? Quite simply: malfunctions must be ruled out. If the measurement of the absence of voltage is carried out with

If the measurement of the absence of voltage is carried out with a wrongly adjusted measuring range - that is, current measurement instead of voltage measurement - and the high-voltage installation, contrary to expectations, is not de-energized, it can flow a very high current in "current measurement" mode due to the low internal resistance of the device.
