Features:

• Wide Voltage Range: Test circuits from 6V to 24V with ease using this versatile tool.
• Convenient Light Bulb: The built-in light bulb makes it easy to see what's going on inside your car's electrical system.
• Accurate Measurements: Get precise readings with the electric measuring pen, ensuring accurate diagnoses every time.
• Easy to Use: Simply insert the test probe into the circuit and read the results on the display.

1. The sharp steel probe can easily pierce the wire insulation to check the circuit.
   
2. The probe pen is very suitable for checking circuits, fuses, switches and wiring in cars, trailers, boats, motorcycles and other low-voltage systems.
   
3. Connect the alligator clip to the ground and test the circuit with the probe. When the light is on, there is electricity.

Product usage:

1. Clamp the measured alligator clip on the ground wire (such as the metal or negative pole of the car).
2. Measure the contact between the pen tip and the conductive metal in the test circuit.
3. If the light bulb of the stylus lights up, it indicates that the measured point has formed a circuit and works normally. On the contrary, the tested point has faults to be checked.

Note:

1. Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.
2. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
