This CFL510G is primarily designed for linemen in both the communication and power industries. Specific capabilities include:


Provides fast and accurate results when uncovering transmission related problems. Designed to be carried on a linesman’s belt and used in the first line of defense when diagnosing and locating cable faults.

Specific line activities identified by this unit include:

  • Bridge taps and splices
  • Presence of water in the cable
  • Opens in tip, ring, or sheath
  • Shorts between tip, ring, and/or sheath
  • Capacitive networks
  • Load coils
  • Wet splices and high-resistance splices


Ideal for testing the physical integrity of cables within a network. The unit is also capable of locating illegal cable taps.

Specific cable conditions identified include:

  • Bends or crimps in the cable
  • Cuts or shorts in the cable
  • Taps and splits
  • Water saturation


An ideal tool for identifying faults on secondary power cables.

This unit identifies:

  • Burnouts in aluminum conductors
  • Good splices, wet splices, and high-resistance splices

The CFL510G is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m/0.3 ft and a 5 km/15,000 ft maximum range depending on velocity factor selected and cable type.

Four output impedances (25, 50, 75, and 100 Ω) are available and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.

The CFL510G has a simple selection option which, together with a four-way control switch, offers an intuitive operation for the user.
