Cable length testers
The cable length tester is an indispensable tool for specialists who work with various types of cable lines. Modern devices allow you to measure the length of telephone, coaxial, network, and other cables with metal cores with high accuracy, and to solve many related problems. The choice of the right model depends on the measurement method used by the cable length tester. In this section, you can buy devices for determining cable length by capacitance as well as by way of the time domain reflectometry (TDR) method. Professional cable testers are capable of not only determining the length of a line but also performing comprehensive diagnostics.
A cable length tester – capabilities of modern diagnostic equipment
Cable testers detect breaks and short circuits with precise distance to the fault, check the correctness of twisted pair cross-connection, perform PoE testing, and the PING test of a network connection. Many models are equipped with a tracing function that allows you to find the required cable in a bundle of wires.
A cable length tester: price depends on functionality
An important feature of modern testers is the ability to work with different types of cables without the need for additional calibration. Many models are equipped with special remote sensors that allow the simultaneous testing of several lines, which significantly saves time when servicing complex cable systems. Built-in data processing algorithms ensure high measurement accuracy even in conditions of strong electromagnetic disturbance.
A modern cable length tester usually features a color LCD display with backlight for easy reading. The devices are equipped with built-in memory for storing measurement data, and some models allow you to record the results on a microSD card. For ease of use in the field, the devices have a long battery life.
