Overview - TDR Cable Fault Locator

This TDR cable fault locator integrates an OTDR, megohmmeter, ohmmeter and automatic bridge into one unit. It is ideal for localization of breaks, shorts, poor electric insulation and other faults of various telephone cables, RF cables and coaxial cables.

Using DAGC (Digital Automatic Gain Control) and Digital Waveform Automatic Recognition technologies, this cable fault locator is able to automatically recognize faults which are not found with manual testing. It also features a field calibration function and performs testing of insulation resistance and loop resistance.

Key Features - TDR Cable Fault Locator

  • Megohmmeter and ohmmeter functions
  • 0 m dead zone test distance
  • Contrast function for 2 waveforms
  • Suitable for 0.32 mm, 0.4 mm, 0.5 mm, 0.6 mm telephone cables
  • Stores 10 testing waveforms and measurement results that can be uploaded
  • USB interface
  • Built-in 2 Ah lithium-ion rechargeable battery
  • Touch color screen

Application - TDR Cable Fault Locator

  • Testing for insulation resistance and loop resistance
  • Automatic detection of the line status including breaks, shorts, poor electric insulation and high line voltage
  • Field calibration function (unknown cable parameter: speed or diameter; correction for distance of cable)
