  NanoTronix Numeric Cable Fault Locator (Model No.:mTDR-010) is the most suitable and low-price instrument for locating a fault such as open and short position in metallic telecom cables. It is unique in its class which utilizes TDR (Time Domain Reflectometry) technology giving users accurate information of the faults based on a specific cables' VOP(Velocity Of Propagation).

The instrument of this cable fault locator is applicable for any cable consisting of at least paired (shielded or twisted) metallic conductors, such as coaxial cables and telephone cables at low cost. It has an automatic internal impedance matching network to allow testing of 25Ω, 50Ω, 75Ω, 100Ω, 125Ω and 150Ω cables.

The Numeric Cable Fault Locator is housed in a rugged ABS enclosure which is dust and weatherproof to IP 42. The instrument of this cable fault locator also comes with a soft carrying case and alligator clip adapter. It is powered by four AA (NEDA 15A or LR6) batteries, which are stored in a compartment on its back.

NanoTronix Numeric Cable Fault Locator (Model No.: mTDR-010) presents automatic VOP calculation allowing efficient measurement for all types of cables - providing auto calculation of VOP of a sample cable: a sample of 10 meters (30 feet) enables even inexperienced technicians to set up and conduct standardized tests to get perfect results every time.
Additional 20 memory spaces are available for storing new VOP settings, which let technicians to conveniently save the VOP values of frequently worked cables for future usage.
