The Electrical Detective: Quickly Diagnosing Faults with the JM-G2704 Test Pen

A sudden power outage or a faulty fixture often leads to a frustrating guessing game: where is the break? Guessing can be dangerous and time-consuming.

The JM-G2704 Non-Contact Electric Test Pen transforms electrical fault finding from a chore into a precise science. It utilizes smart acoustic and visual alarm technology to give you the clear answers you need, allowing you to troubleshoot with speed and total confidence.

The JM-G2704 is a game-changer when tackling hidden faults within insulated wires:

  • Line Breaks Detection: When an energized wire breaks inside the insulation, the pen can trace the line. By probing along the charged wire, you can detect where the voltage signal abruptly stops.

  • Intelligent Acoustic and Visual Alarm: The strength of the intelligent acoustic and visual alarm allows you to instantly determine the exact break point. When one end is charged and the other is not, the pen clearly indicates the fault location, saving you from damaging perfectly good insulation.
