      The Megger CFL510G TDR Hand-held Time Domain Reflectometer is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. The Megger CFL-510G 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 Megger CFL510-G has a simple selection option which, together with a four-way control switch, offers an intuitive operation for the user.

       

      Applications
      This Megger CFL510 G is primarily designed for linemen in both the communication and power industries. Specific capabilities include:

      Telephony

      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
      CATV/Cellular

      Ideal for testing the physical integrity of cables within a network. The Megger CFL510G 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
      Power
      An ideal tool for identifying faults on secondary power cables. The Megger CFL510G TDR identifies:
      • Burnouts in aluminum conductors
      • Good splices, wet splices, and high-resistance splices
      • Shorts between phases
