Using Tips:

*Before use, visually inspect the test pen housing for cracks or ruptures, as well as for moisture or water ingress. Only after passing the inspection can it be used. If you suspect any issues please immediately send the test pen for repair.

*When using the voltage measurement function, it is prohibited to touch the metal knife bar at the front end with your hands, otherwise it may cause personal electric shock accidents.

*Do not apply voltage exceeding the rated voltage marked on the tester. Be particularly careful when testing AC voltages above 30V to prevent electric shock hazards.

*Comply with local and national safety regulations.

*Use appropriate protective equipment in accordance with local or national regulatory requirements.

Circuit Break-point Detection

The so-called breakpoints cannot be directly measured and it is necessary to find a suitable area to measure them. For example, when measuring a wire, if the test pen is adjacent to the wire, the green light will light up. The green light on indicates the electric field induction area. In this induction area, the test pen will light up with a green light, and the breakpoint will be located at the boundary of the induction area. There are various types of wires and different lines with different measurement results, which can be discovered with a little exploration

Live/Neutral Wire Detection

Live wire detection : When the screwdriver head comes into contact with the power supply, the red and green indicator lights will light up simultaneously, indicating that it is live (voltage>70V, the red indicator light will light up, and the buzzer will sound).

Neutral wire detection : When the batch head comes into contact with the power supply, the green light lights up, indicating the zero line or ground wire.

Non-contact AC detection

When the screwdriver induces the voltage signal around the socket, the green light flash.
