Inline retention: The test clips offer convenient inline retention. After the clips are attached to the leads, the test leads can be removed from the clips for testing in another location. Quick circuit identification: Red and black colorcoded barrels provide quick, ataglance circuit identification. Costeffective and durable design: The design is costeffective and convenient; it can be quickly removed to expose the puncture tip for sharpening, extending the life of the product. Precise puncture capability: Puncture clips allow the user to provide the precise pressure required to puncture the insulation of various wire types and sizes. Use case: Field electrical diagnostics Clip onto a wire harness to establish test contacts, then detach the leads to continue testing at a different point without losing the clip. Use case: Panel and harness troubleshooting Use the colorcoded red and black barrels to quickly distinguish positive and negative circuits during diagnostics. Use case: Accessing conductors for measurement Apply controlled puncture pressure with the puncture clips to access conductors inside insulated wires of various sizes, then sharpen the puncture tip as needed to extend tool life.
