Time Domain Reflectometer | TDR-420
R32,905.00 ex vat
Time Domain Reflectometer - Overview

TDR-420 is a handheld Time Domain Reflectometer designed to locate and identify faults in power, telecommunications and data cables. Specifically made for electrical wholesalers, cable dealers, electrical installation companies, maintenance personnel at manufacturing plants and building personnel. This TDR-420 reflectometer allows you to measure the length of a cable as well as determine the distance to damage or impedance variation in conductors with metal wires in the range of 0.6 m -6000 m. With a measuring shortest range selected at 7 meters and a dead zone of 0.6 meters, this allows one to locate damages at a very close distance from the place where the device is connected.

Time Domain Reflectometer - Features

Standard Programmable Resistor SRP-10G0-10T0

Standard Programmable Resistor - Overview

The SRP-10G0-10T0 calibrator, which has a range from 10GΩ to 10TΩ, is a source of high resistance which is used as a standard in calibration and testing of analogue and digital insulation resistance meters. The selected resistance can be maintained for a long time under external direct voltage up to 10 000 V, provided that the current in the measuring circuit does not exceed 3 mA. The required resistance is set by the user using the calibrator's touch keypad or via an external PC application. The required value is set automatically thanks to the switching of a precise resistance matrix. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.
