A cable tracer is a device that can trace cables and wires in walls and floors without damaging the walls or insulation. The tracer can also be used for finding short circuits in wires or detecting open circuits.
Ideal for applications such as underfloor heating systems, locating buried utilities before you dig, locating telephone and communications lines.
There are three technologies that use cable tracing:
Tone tracing – Can only be done on live cable. You place an electric signal at one end of the cable using a tone generator and then use your cable tracer to trace the signal. They have traditionally been analogue but more recently digital or asymmetric tone tracers have started to appear on the market.
Continuity testing – Provides ideal way to locate and label your network cabling, up to 20 cables at a time.
Hub blinks – Only works if the cables you are looking for are connected to a live network. They blink as they find the hub blinks.
