- AC Voltage Display and Buzzer Alarm: This electric test pen provides a clear AC voltage display and an audible buzzer alarm. Simply touch the live wire with the pen tip while your hand contacts the touch electrode for accurate voltage readings, accommodating variations in human body grounding. - Live Wire Identification: Quickly and sensitively identify live wires with this test pen. When the pen tip is inserted into a hole and your hand touches the touch pole, a red screen and beeping sound confirm the presence of a live wire. A green screen reading 0V indicates a neutral wire, ensuring safe and efficient use. - Intelligent Non-Contact Voltage Detection: The test pen features non-contact voltage sensing, allowing for detection of nearby AC voltage without direct contact. The screen indicator increases from LOW to HiS, and the beeping sound intensifies as the power source approaches, enhancing safety during inspections. - Line Breakpoint Detection: Effectively troubleshoot electrical lines with the pen's breakpoint detection capability. A HiS indicator and a beep signal a continuous line, while a LOW reading indicates a disconnection, making it easy to locate issues in wiring. Applications: - Ideal for electricians or DIY enthusiasts needing to safely test electrical systems. - Useful for homeowners to check for live wires before performing repairs or renovations. - Essential for maintenance teams to quickly diagnose electrical faults in machinery or equipment.
