Types of measurements provided by the TDR unit: cable length measurement; measuring distances to impedance discontinuities or damages; measurement of the velocity factor of the line to its length known; determines the nature of injuries. Types of measurements provided by the cable bridge unit: loop resistance measurement; insulation resistance; measurement of capacitance; measurement of DC and AC; resistance difference definition; determination of the distance to the point of reducing the insulation; determination of the distance to the point of breaking the cable core; determine the distance to a short-circuit cable wires; insulation test voltages. Sphere of application TDR-10M2 is used to control the laying and operation of the following types of cables: System Cables Communications; Signal and Control Cables; Power cables; Aerial cable lines; Computer Networks; TV and radio cable lines;
