Probe pens are great for checking circuits, , switches, and wiring in cars, ilers, boats, motorcycles, and other low-voltage syst.Ground the alligator cls and test the circuit with the probe. If the light comes on, there is power.Conly, the point under test there is a fault, to be investigated1.2M Spring Cable: The cable is extensible for you to and the total length is 1.2M, which can meet your most needs.1. Hold the alligator cl of the measuring to the ground wire (such as the metal or negative pole of the car)2. to measure the head of the electric pen contact to test the conductive metal in the circuit3. If the light of the stylus will light up, it means that the point under test has constituted a circuit and is working properly.Measuring ranges: 6-12-24 VColour:Photo ColorMaterial:plasticPackage Contents:4 x Circuit Only the above package content, other products are not included.Note: Light reflection and different displays may ca the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
