Cable fault locator (reflectometer) TDR-420 WMPLTDR420 /T2AU
Parameters:
The TDR-420 reflectometer is a handy digital pulse locator (TDR - Time-domain Reflectometer) designed to identify and locate faults in power, telecommunications and telecommunications cables. The TDR-420 reflectometer allows you to measure the cable length and determine the distance to damage or impedance change in the range from 4 to 6000 m in cables with metal conductors. The shortest measurement range with a range of 7 meters and a dead zone of 0.6 meters allows you to locate faults very close to the device connection point. Two cursors allow you to determine the distance to two damages at the same time and the distance between them. Thanks to the color display with a resolution of 320 x 240 pixels, the location of damage is precise and the results are easier to interpret. Unfavorable weather conditions during measurement work are frequent problems faced by assembly teams and maintenance services. Thanks to its unique housing, the TDR-420 device has a protection level of IP67. This means dustproof and protection against water ingress during short-term immersion. Therefore, working in a very dusty area or accidental contact of the device with water will not affect the correct operation of the reflectometer. Features of the device: possibility of damage-free localization of damages and impedance changes of tested cables and wires, such as: short circuits, breaks/cable termination - useful during inventory of warehouses and stores, connectors (joints), branches, moisture in the section, wet connector, other impedance changes. Single ONCE measurement mode, CONT continuous scanning mode, TONE acoustic signal generator, Two cursors for marking two places of damage with indication of the distance between them, Built-in help system for easier interpretation of the reflectogram, 11 available measurement ranges from 7 m to 6000 m, "zone "dead" measurement limited to 0.6 m, 3.5" color LCD display, sensitivity manually set, impedance matching adjustment up to 200 OHM (measurements of pre-insulated pipes), propagation coefficient adjustment from 10% to 99%, tight and mechanically durable IP67 housing . small dimensions and weight.
