The Megger CFL535G is a dual-channel, high resolution, compact Time Domain Reflectometer with a minimum resolution of 0.3 ft/0.1 m and a 60k ft/20 km maximum range, depending on the velocity factor selected and the cable type. Five output impedances are available (25, 50, 75, 100, 125 ohms) and the velocity factor can be set between 0.2 and 0.99.
Megger's Xpert mode allows one-button adjustment of range and gain and positions the cursor to the first major event on the cable. A second press of the Xpert button and the CFL535G jumps to the next detected disturbance. Manual operation is also available and allows full override access to refine the response. The Diamonds judges liked how easy the product was to use and noted that it appears to get the tech closer to the fault, which will save time.
