TDR 4000 provides you with 10.4-inch bright high-contrast TFT display with touchscreen. The 800*600 pixels resolution makes the picture sharp. The touchscreen allows an operator navigate through the menu fast and easy.An alternative way of navigation is included. It is provided with a control knob.
TDR 4000 integrates a multiple ways of fault prelocation. It can be used either as a standalone device in TDR mode or in a conjunction with HV-module. (e.g. Cable test van or Surge wave generator), working in arc reflection (ARC), impulse current (ICE) and decay modes. A high-capacity internal battery allows working up to 8 hours.
TDR 4000 has both RS-485 and USB interfaces. The package content includes software for PC (optional), which allows working with saved reflectograms. The firmware is easily updated through USB interface by inserting a flash drive.
Battery powered Digital Impulse Reflectometer (TDR) TDR 4000 designed for determining the distance to a fault in communication and power cables.
Key Features
  • Determining the distance to a fault or discontinuity in symmetric and asymmetric cables using a location (time domain reflection) method.
  • Measuring the length of a cable (including those wound on a drum) or distance to a fault or a short circuit.
  • internally or using a supplied PC software.
  • As part of a Cable Test Van,determining the distance to a fault or discontinuity in cables with length of up to 100 km for all possible fault types without the need of preliminary full cable sheath burning.
