The Megger CFL 510G Time Domain Reflectometer is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1m/0.3ft and a 5km/15,000ft maximum range depending on velocity factor selected and cable type. Four output impedances (25, 50, 75, and 100Ω) 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. This CFL510G 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 by this unit are:
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 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
Power: 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
