The 2-pole voltage tester is suitable for safe voltage measurement indoors and operates without batteries. An integrated LED display visually indicates the measured voltage. Voltages between 6 and 400 volts are detected for both direct and alternating current. Low voltages up to 24 volts are displayed in green, while dangerous voltages from 50 volts are shown in red. The polarity for direct current is also indicated by an LED. The voltage tester is approved for measurements in category CAT III up to 400 volts. Functions such as continuity testing, phase rotation, or phase testing are not included. A measurement point illumination is not integrated. The device comes with screw-on contact sleeves for testing at sockets.
