Megger CFL510G Handheld Time Domain Reflectometer
Introduction of Megger CFL510G
The Megger CFL510G Handheld Time Domain Reflectometer (TDR) is a highly portable device designed for fault location in cables and measuring the length of both metallic and fiber optic cables. This TDR model is recognized for its ease of use and portability, making it an essential tool for technicians working in telecommunications, utilities, and network services.
The CFL510G is compatible with twisted pair copper and coaxial cables and offers a fine resolution of 0.1 meters (0.3 feet). It can measure cable lengths up to 5 kilometers (15,000 feet), depending on the cable type and selected velocity factor. The device supports four different output impedances (25, 50, 75, and 100 ohms) to meet various cable testing needs, and the velocity factor is adjustable between 0.2 and 0.99, allowing for precise customization to specific cable testing scenarios.
Megger CFL510G Key Features
- Dual cursors for pinpointing faults
- Auto setup for instant use
- 2 ns pulse width virtually eliminates dead zones
- Unique trace ‘Hold’ feature for comparison between cables
- IP54 rating
- Designed for use on all metallic cable pairs
