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.
