Product usage method
1. Clamp the alligator clip of the measuring wire onto the grounding wire (such as car metal or negative electrode)
2. Place the tip of the measuring pen in contact with the conductive metal in the circuit to be tested
3. If the light bulb of the measuring pen holder lights up, it indicates that the measured point has formed a circuit and is working normally. On the contrary, there is a fault at the tested point that needs to be investigated
