Bipolar voltage tester in a solid housing with flexible cables in silicone insulation. Detects and measures AC and DC voltages in the range of 6 to 1000 V. The result is indicated on the LCD display and via LED indicators. The tester also allows you to:
- check the phase rotation sequence in three-phase systems
- check the voltage in low impedance mode (to eliminate noise)
- test the operation of RCD switches with a rated current of 30 mA or less
- perform circuit continuity test and measure resistance up to 1999 ohms
Measurements in low light conditions are facilitated by the built-in LED flashlight. Measurement safety is supported by a solid and sealed housing with IP64 standard. The set includes screw-on probe caps to facilitate measurements in sockets. The meter meets the requirements of CAT III 1000 V / CAT IV 600 V surge protection categories.
