This 3-in-1 Tracer/Toner/Cable Tester from Tech Choice is a professional tool used to test and troubleshoot RJ45, RJ11, and BNC cables. It can also be used to trace and identify individual wires within a wire bundle or group and can provide talk testing functionality between telephone units. The tester is composed of two main units: the Tone Generator/Cable Tester and the Amplifier Probe with sensing tip. Each unit is constructed of plastic with the edges covered in rubber to improve grip. Each unit is powered by a 9 volt battery and two batteries are included in the packaging.
- In Talk Batt mode, the tester provides the power and closes a telephone circuit to allow the phones to be tested for operation and the wires to be tested for continuity and clarity.
- The tester has an auto-off functionality that kicks in after 20 seconds of non-use in all modes except the Toner and Talk Batt mode.
- These latter two modes will remain on without activity for 30 minutes before the tester automatically shuts down.
The Tone Generator portion of the tester is used to send a tone down an attached cable. The Amplifier Probe is then used at the other end to test individual cables in a bundle or group to find the one with the tone, thus identifying the cable. The Amplifier Probe can also be used at various points along a cable length to locate a break in the cable.
