The Cable Tracker is designed to identify and trace wires or cables within a group without damaging the insulation.For telephone line, it can identify some state in the line, and more convenience to install, debug, maintain telephone line.There is a Sender(MS6812-T) and a Receiver(MS6812-R)included in The Cable Tracker
● Sound and Light Instruction
● Cont and Tone LED Light
Applications
– Judge Continuity of the Cables or Wires
– Track the Cables or Wires, and Diagnose the Break Point
– Receive the Tone Signal on the Cables or Wires(Telephone Line)
– Identify the State in the Working Telephone Line(Clear, Ringing, Busy)
– Send a Single Solid or a Dual Alternating Tone to the Target Cables or Wires
