TDR Cable Fault Locators

CableTool Multifunction Cable Meter

The CableTool CT50 provides contractors,CATV, low voltage installers, or anyone involved in the installation or maintenance of metallic cables with the capability to quickly find faults in cables up to a distance of 2500 feet.


Cables can be damaged during or after installation. Typically the damaged section is hidden from view behind walls, above ceilings or buried underground. Using TDR technology, the CableTool diagnoses cable faults with no launch or dead zone and an accuracy to ±2%.


Simply select the appropriate cable type from the pre-stored library or enter the cable NVP, attach the leads to two conductors of the cable and with a single press of a button the length of the cable or distance to an open or short is displayed.

The CableTool CT50 will also inject a tracing tone onto the conductors to trace cables with a standard tone probe.

(A kit version, the model CTK5015 includes the model CT15 tone probe).


Voltage on the wires up to 250v is continuously measured by the built in, true RMS voltmeter and is displayed to warn of a potentially unsafe condition.


The CableTool makes it easy for installers to know the amount of cable remaining on a spool or in a box before pulling a run. When multiple runs are being installed in the same area, the first run can be measured to accurately determine the total amount of cable required to complete the job. Checking cable inventory prior to starting a job eliminates unplanned trips to buy more cable.


The universal banana jack test lead connectors allow for a wide range of adapters for any connector type. In addition, a BNC and F adapter are included. A carrying case and 4 "AA" batteries included.
