## Overview

The Megger CFL510G is a handheld Time Domain Reflectometer featuring 0.1m resolution and ±1% accuracy, powered by AA batteries. Its 2 ns pulse width minimizes dead zones, while dual cursors and a unique trace hold function enable precise fault detection and cable comparison. With an IP54 rating, it’s engineered for reliable field use on all metallic cable pairs.

## Description

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 Ohm) 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. Backlit graphics monochrome LCD (256 x 128). Adjustable display contrast. Resolution to 0.1 m. For use on telecom circuit or 150 V CATIV power circuit. Power blocking filter not required. Environmental protection to IP54. Auto selected output impedance (between 25, 50, 75 and 100 ohms). 2 ns pulse for near-end fault location. Auto option selecting gain and pulse for each range. Display distance in meters or feet. Applications: This CFL510G is primarily designed for linemen in both the communication and power industries. Specific capabilities include: Telephony, CATV/cellular and power. Except where otherwise stated, this specification applies at an ambient temperature of 68 degrees F. Accuracy: +/-1 percent of range ± pixel at 0.67 VF. Input protection: Complies with IEC61010-1 for connection to live systems up to 150 V CAT IV when used with the optional fused test lead set. Output pulse: 5 V peak to peak into open circuit. Pulse widths determined by range and cable. Gain: Set for each range with three user selectable steps (in manual operating mode). Velocity factor: Variable from 0.2 to 0.99 in steps of 0.01. Automatic TX null. Power down: automatic after 5 minutes with no key press. Stays on for one minute with no key press backlight. Power: Five AA (LR6) type batteries, manganese-alkali or nickel metal-dydride cells. Battery life up to 14 hours (typical). Operational temperature: 5 to 122 degree F. Storage temperature: -4 to +158 degree F.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A hand-held TDR, Time Domain Reflectometer (TDR)
*by G***Y on June 27, 2013*

This product is used to troubleshoot, test and find problems with cables. The unit sends out pulses along the cable that are reflected back. The TDR then calculates distances to "events" based on time and cable type. The "events" are detected by changes (increases or decreases) of impedance along the cable being tested. A map of the cable is then shown on the TDR display.A great product for electrical contractors working on power and communications installations. Also QA inspection of wiring. Also Linemen in power and communication industries.Markets for this TDR include: Airports, CATV, Commercial Buildings, Electrical Substations (utility/industrial), Government/Military, Manufacturing, Petrochemical, Telecommunications and Universities.Megger TDR model CFL510G is designed to work on twisted pair copper and coax cable. It has the capability of a 2 ns pulse width which virtually eliminates dead zones, and is useful for finding near-end faults. At 2 ns the dead zone is 3 feet.Main Functions:1. Locating cable faults.2. Test integrity of power, control or communication cables.3. Measures distances (meters or feet) to "events" such as a fault, broken or pinched cable, bends or crimps, loose connection, opens and shorts, taps, bridged tap, water problems, splices, frayed cable, splitter and other additional activities identified.Wide Range of Cable Types:Low voltage power cablesCoaxTwisted pair dataTwisted pair communicationAll metallic cable pairsSome Features Are:Multi step range control: 30 ft, 75 ft, 300 ft, 750 ft, 3000 ft, 7500 ft, 15000 ft.Trace HOLD feature for comparison between cables.5 minute power down.Indoor/outdoor use, rated to IP54.3 year warranty14 hour battery lifeSingle cursor - distance from start of cable to cursor.Dual cursors - distance between 2 points.Power blocking filter not required - use on energized cable.Auto selection feature - most effective parameters chosen.
