Without direct metallic contact, this kit can quickly and accurately trace and identify the specific wires within a bundle, at a cross-connect point or remote end.
It works with all types of wire and cable, including twisted pair, multiconductor cable, de-energized AC wire, speaker wire, coaxial, security & alarm cable and LAN cable.
TRACER-A(DR-77A) is a tone generator, which applies its tone signal to a wire pair that the user want to identify at the far end or within a bundle. For the easy access to wires, it has test lead wires with ABN clips and modular plug(RJ-11). Belt clip is convenient for the easy carry.
Independently it can work to test polarity and continuity.
TRACER-B(DR-77B) identifies the specific pair through the bell sound and LED light. Its recessed on/off control button prevents the accidental push.
TRACER-A & B can be purchased separately.
