Time-saving: Quick voltage testing through non-contact measurement. Efficiency: Thanks to the internationally adapted measuring tip, the voltage tester can be used with all sockets worldwide. Facilitates your work: The integrated LED flashlight ensures optimal lighting conditions and simplifies the electrician's work in challenging situations. Flexibility: The voltage tester covers a wide voltage range from 12 to 1,000 V AC. Application: For detecting and locating live conductors, cable interruptions and breaks, blown fuses, defective bulbs in light strings, as well as single wire detection. Before starting any electrical installation, electricians must ensure that the work environment is free of voltage. To test electrical alternating fields or locate suspected sources of error, a voltage tester is required. A first indication of whether voltage is absent can be obtained with the non-contact Wiha voltage tester thanks to its optical and acoustic signals. When switched on, the permanently green LED indicates readiness for use. During voltage testing, the LEDs light up from blue (weak) to orange and red (strong) depending on the strength of the electrical alternating field. Two AAA batteries are required for use, which are included in the delivery. If the device is not used for 4 minutes, it automatically turns off to save energy. An integrated LED flashlight allows for illumination of measurement points in dark environments and can be manually turned on and off for use as a flashlight. The voltage tester with clip fits comfortably in any shirt or pants pocket due to its handy size. The single-pole voltage tester complies with the standard EN 61010-1 / IEC 61326 and is designed for CAT IV 1,000 VAC.
