With this handy tool, you can quickly and easily locate short circuits, open circuits, broken wires, power leaks and even wires. How does it work? Simple! Connect the tone generator to the cable and use the measurement probe to detect the cable break. Once the cable break is found, the audible signal stops so you can repair it quickly, without opening the insulation layer of the wire. This cable tester can be used to test different types of cables, including: Telephone cables (RJ45, RJ12) Network cables General electrical wiring Audio and video cables Perimeter cables for robotic mowers
