## Long description

The Wiha 43798 Line Voltage Detector is a single-pole, contactless tester for AC voltages from 90 to 1,000 VAC. Supplied with two AAA batteries, this compact tool provides a quick visual indication of the presence of voltage through a permanently green LED when ready and a red LED when voltage is detected. Its slim form factor with push-on clip fits into a shirt or trouser pocket. The measurement tip is designed for international socket variants and the device is rated to CAT IV 1,000 VAC and complies with EN 61010-1 and IEC 61326.
Advantages
The contactless detection method enables fast, non-invasive identification of live conductors without physical contact. Built-in LEDs provide clear visual feedback that is visible in daylight, and the included AAA batteries allow immediate use. The compact size and pocket clip improve portability, while the internationally adapted measurement tip makes the detector suitable for use with different socket types. Compliance with CAT IV 1,000 VAC and relevant standards ensures the device meets common safety requirements for line voltage detection.
Suitable for
Checking whether sockets, cables or single wires are live
Locating cable breaks, blown fuses and defective bulbs in lighting chains
Quick voltage checks before electrical installation or maintenance

How to use
Insert the two supplied AAA batteries and switch the detector on. Verify correct operation by testing the device on a known live voltage source before starting work. Hold the measurement tip close to the conductor, socket or connection to be tested; the permanently green LED indicates the tester is ready, and the red LED will illuminate if voltage is present. After testing, switch the detector off and store it using the push-on clip in a pocket or tool bag.
Usage recommendations
Test the voltage detector on a known live source before and after each use to confirm proper function. Do not rely solely on the detector for proving absence of voltage in critical situations — follow applicable safety procedures and use additional verification tools if required.
