70-250v Responsive Electrical Tester Pen, Waterproof DC/AC Voltage Detector Pen Non-contact with Light for Live/Null Wire Judgment Warm Tip: 1. Your hand should feel the bottom of the pen, where the screw bar is, otherwise you can't tell if the cord is live or not. 2. When the pen touches an energised line socket, the light will come on, indicating that the line is live. The light will not come on when the pen touches the ground socket. 3. A slight shaking will also cause the pen to light up slightly due to static electricity in the air. 4. This is the perfect addition to your kit with our responsive electrical tester pen. 5. Made with high quality and durable accessories and with 4 functions on it so you are always prepared.
