Before starting electrical installation work, electricians need to guarantee that their work environment is free of any live electrical wiring. 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 and audible signal. Once the tester is switched on, the permanently green LED indicates that the tester is ready for use. During the voltage test, the LEDs will light up blue (weak), orange, or red (strong), depending on the strength of the alternating electric field. Two AAA batteries are required to operate the device. These are included in the delivery. The device switches off automatically to save energy if it is not used for four minutes. An integrated flashlight allows the user to illuminate the measurement point in dark environments and can be switched off and on manually for use solely as a flashlight. 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 suited to international usage. Designed for CAT IV 1,000 VAC, the single-pole voltage tester complies with EN 61010-1/IEC 61326.
