Before starting electrical installation work, electricians need to guarantee that their work environment is free of any live voltage. A voltage tester is required to test alternating electric fields or probable sources of error. The contactless Wiha voltage tester will give an initial indication of whether an area is live or not thanks to an optical signal.

Once the tester is switched on, the permanently green LED indicates that the tester is ready for use. If a voltage is detected, the red LED lights up, which can also be easily seen in daylight. Two AAA batteries are required to operate the device. These are included in the delivery. With its push-on clip, the voltage tester snugly fits into any shirt or trouser pocket thanks to its handy size.

The voltage tester is suitable for all socket variants worldwide thanks to its measurement tip adapted to international usage. Designed for CAT IV 1,000 VAC, the single-pole voltage tester complies with EN 61010-1/IEC 61326.

Application: Used to detect and locate live electrical cabling and wires, breaks and cable interruptions, blown fuses, defective light bulbs on light chains and single wires.

Note: The voltage tester should be tested on a known voltage source before and after every use to ensure it functions correctly.
