Handheld Voltage Tester
This BENNING DUSPOL® digital (item no. 050263) is a handheld voltage tester designed for measuring AC and DC voltages with functions specified by the manufacturer. The device measures AC TRUE RMS 1–1000 V and DC up to 1,200 V, displaying measurement values on a backlit LC display. The DUSPOL® digital is shown with VDE/GS approval on the manufacturer's website.
Features and Operation
- Digital LC display with automatic backlight.
- Phase sequence/direction of rotation test and single-pole phase indicator.
- Polarity display for DC.
- Continuity test with buzzer and yellow LED indicator.
- Non-contact cable break detector (non-contact) with yellow LED.
- Load switching via push buttons (built-in vibrator motor during testing) to distinguish real voltages from capacitive/inductive voltages.
- Vibration alarm upon load connection; built-in thermal protection for prolonged load.
- IP65 enclosure rating and overload categories CAT IV 600 V / CAT III 1000 V.
Documentation

Typical Applications
The following applications are directly derived from the manufacturer's functional description:
- Checking and displaying AC voltage in the range 1–1000 V TRUE RMS.
- Checking and displaying DC voltage up to 1,200 V as well as polarity determination.
- Single-pole phase indication and phase sequence/direction of rotation test in grounded networks.
- Continuity and diode test as well as localization of cable breaks (non-contact detection).
- Separation of real voltages from capacitive/inductive interference voltages when a load is connected (load switching).
