1. Insulation Testing: The clip set can clip onto insulated wires without removing the insulation. Suitable for car electrical circuits, use with multimeters, voltage testers, and spot detection. 2. Non Breaking Puncture Probe: Car wire probe clip and detection probe pins set. The red and black color coded barrels provide quick circuit identification. 3. Portable Size: Insulation test tools, 0.6 cm x 1.93 cm, fits for most plug pins. 4. Durable Material: Puncture probe clip set; the probes are designed for strength and wear resistance; adjustable detection size. 5. Use scenario automotive diagnostics: Use the clips to test circuits in a car's electrical system without stripping insulation, enabling quick circuit verification in confined spaces. 6. Use scenario electronics workshop: Pair with a multimeter or voltage tester for spot detection and circuit verification, with color coding aiding fast identification. 7. Use scenario field service and wiring inspection: Compact, durable probes with adjustable detection size support testing of various wire gauges during onsite inspections.
