Time-saving: Fast voltage testing thanks to non-contact measurement. Efficiency: Thanks to the internationally customised measuring tip, the current tester can be used for all sockets worldwide. Flexibility: The current tester covers a wide voltage range from 90 - 1,000 V AC. Application: For detecting and localising live conductors, cable interruptions and breaks, blown fuses, defective lamps on fairy lights and single wire detection. Before starting an electrical installation, electricians must ensure that the working environment is de-energised. A voltage tester is required to test alternating electrical fields or locate suspected sources of faults. The Wiha non-contact voltage tester provides an initial indication of the absence of voltage thanks to its visual signal. After switching on, the permanently lit green LED indicates that the device is ready for operation. If voltage is present, the red LED lights up, which is easy to read even in daylight. Two AAA batteries are required for use, which are included in the scope of delivery. Thanks to its handy size, the voltage tester with clip-on clip fits comfortably in any shirt or trouser pocket. The single-pole voltage tester is subject to the EN 61010-1 / IEC 61326 standard and is designed for CAT IV 1,000 VAC.
