connectivity test
• Cable identification (with Remote Unit or Locators)
• Cable length up to 300m, calibration facilities for accurate length measuring
• Amplitude and location of reflections are provided by an in built Time Domain
Reflectometer.
• Tone generator for tracing hidden cable paths and wire determination
• Talk function for communication over the cable link (with optional Talk Remote
unit)
• Supports coax and twisted pairs cables
The instrument is supplied with all accessories necessary for carrying out the tests.
