TFL-B5 1 Cable Fault Pre-Locator

Cable Fault Pre-Locator

This handy microprocessor-based cable fault prelocator is a user-friendly, portable tool designed to quickly and accurately identify faults in telecommunication, signal, and pilot cables. It cleverly combines Time Domain Reflectometer (TDR / Pulse Reflection) and Intelligent Bridge Testing methods, making it super effective at pinpointing issues like open or broken circuits, short circuits, cross faults, earth faults, and insulation problems.

On top of that, it features IR testing capability, which lets it measure and show insulation resistance in Mega Ohms while in bridge mode. With its compact and sturdy design, plus an 8-hour battery life, it’s perfect for dependable use right on-site.

  • TDR mode & Bridge mode
