Inline mounting provides added convenience - Attach the test clip securely to wires, then remove the clip from the line to conduct tests elsewhere as needed. Cost-effective and practical design - The design allows quick removal to expose the piercing tip for sharpening, extending the life of the clip and avoiding full replacement like other models. Precise insulation piercing with piercing clamps - Use the piercing clamps to apply the exact pressure required to pierce insulation across different cable types and sizes. Easy circuit identification and visibility - Red and black color-coded cylinders enable quick circuit identification, while the bright yellow body is easy to locate in low light. Use scenarios - In a vehicle electrical system, install the clips on wires for initial testing, then move the clips to different locations for subsequent checks without re-wiring. - During insulation integrity checks, apply controlled pressure with the piercing clamps to pierce insulation on various cable types and sizes without damaging conductors. - In dim workshop or field environments, rely on the yellow body and color-coded cylinders to quickly locate and identify components during testing.
