Application: For use in hazardous areas and for the detection and location of live conductors, cable breaks, blown fuses, single-strand detection Before starting an electrical installation, electricians must ensure that the working environment is voltage-free. A voltage tester is required to test alternating electric fields or detect suspected sources of error. The non-contact Wiha voltage tester gives you an initial indication as to whether there is no voltage thanks to an optical and acoustic signal. After switching on the permanently green lit LED indicates the operational readiness. During voltage testing, the LEDs light up, depending on the strength of the alternating electric field, from blue (weak) to orange to red (strong). Two AAA batteries are required for use, which are included in the delivery. If the device is not used for 4 minutes, it switches off automatically in order to save energy. A built-in LED torch enables measurement points to be lit in dark conditions and can be used as a torch by manually switching the torch on and off. The voltage tester with attachment clip fits comfortably into any shirt or trouser pocket thanks to its handy size. Thanks to the internationally adjusted measuring tip, the voltage tester is suitable for all socket versions of the world. The single-pole voltage tester is subject to the standard EN 61010-1 / IEC 61326 and is designed for CAT IV 1,000 VAC. Furthermore, the tool is approved according to the ATEX standard for use in hazardous areas (category II).This text is machine translated.
