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
