Features 1、Non-Contact Voltage Detection (NCV): Detects the presence of voltage without making physical contact with the electrical source. Ensures user safety by allowing voltage detection without the risk of electric shock, making it ideal for quick and safe inspections. 2、LCD Digital Display: Provides a clear and precise digital readout of the measured voltage. The LCD display ensures that users can easily read the voltage levels, enhancing accuracy and reliability in various environments. 3、Sound and Light Alarm: Alerts the user with both visual and auditory signals when voltage is detected. The dual alarm system provides immediate feedback, ensuring that users are promptly aware of potential hazards, even in noisy or dark conditions. 4、Zero FireWire Recognition: Identifies the live and neutral wires in a circuit. This feature helps prevent wiring errors and enhances safety during electrical installations and repairs. Touch the touch pole of the electric pen with your hand and insert it into the socket for identification. 5、Automatic Shutdown: Automatically turns off after 3 minutes of inactivity to conserve battery life. The automatic shutdown feature extends the battery life, ensuring that the device is ready for use whenever needed without frequent battery replacements.
