Black Box Cable Length Meter with Fault Finding - Cable Length Testing, Video Signal Testing, Open Circuit Testing, Short Circuit Testing, Voice Signal Testing - 4Number of Batteries Supported - TAA Compliant

Tests length, opens, or shorts present on voice, data, and video cables up to 3000 feet long.
Spread Spectrum Time Domain Reflectometry (SSTDR) works in all wire environments and is immune to voltage, current, or data disruptions.
Determines cable length with 1% accuracy, identifies cable faults, and can be calibrated to the Nominal Velocity of Propagation (NVP) for any cable.
Holds up to two different NVP values for multiple cable tests.
