General description The 5 Pack Voltage Tester Pen is an intelligent non-contact induction test pen designed for detecting voltage in various applications. It features a user-friendly design with a two-color LED indicator that helps distinguish between live and zero lines. The pen is compact and portable, making it ideal for electricians and DIY enthusiasts alike. Technical specifications Product type: LED electric screwdriver pen Bit head material: Vanadium steel Measuring range: 24~250V Drill diameter: 3 mm / 0.1 in Battery model: 3 AG3 button batteries (included) Product material: ABS insulating anti-fall Usage To distinguish live and zero lines, place your hand on the cap and touch the pole, then insert the pen into the live air. The green light indicates the zero line, while the two-color light indicates the live wire. For disconnection point judgment, the pen can quickly determine if the line is normal. If the green light does not illuminate, the line is disconnected; if it lights up, the line is normal. For electric switch detection, touch the contact rod with the pen. If the inner core of the wire is intact, the green LED will light up; if not, it indicates poor contact.
