Product Information

1. Sharp steel probes can easily pass through wire insulation and inspect circuits.

2. Probe pens are very suitable for checking the circuits, fuses, switches, and wiring of low-voltage systems such as cars, trailers, boats, motorcycles, etc.

Product Usage:

1. Clamp the measured crocodile clip onto the grounding wire (such as the metal or negative pole of a car)

2. Measure the contact between the pen tip and conductive metal in the test circuit

If the light bulb of the stylus is on, it means that the measured point has formed a circuit and is working normally

Be careful:

Due to different world voltages, please allow a tolerance of ±1.5 V.
