Megger, a manufacturer and supplier of test equipment and measuring instruments for electrical power applications, offers a handheld time domain reflectometer (TDR) that locates faults on mixed paired metallic cables. The CFL535G can test the capabilities of connections and locate faults for up to 12 miles.
This high resolution, compact TDR features dual channel capability and dual aspect display. Megger’s CFL535G allows technicians to compare cable pairs to each other and determine if one is faulty, based on differences shown on the TDR.
For use by telecommunications technicians, electrical service contractors as well as cable television companies on all metallic pairs including twisted pair copper, concentric or coax cables, this handheld unit is used during cable installations. The CFL535G establishes a benchmark for future comparison, measures cable length, locates and evaluates splices and joints and detects cable taps.
The cost-effective CFL535G features an ultra-fast 2 ns pulse width that nearly eliminates dead zones and provides a real time trace for tested cables, giving quick and accurate results. It also offers two inputs that enable simultaneous measurements of two different cables.
An auto set-up mode for instant use is incorporated into the TDR. This feature helps determine the impedance of the cable under test, sets the instrument accordingly and selects the optimum gain and pulse width chosen by the operator.
