The MapMaster Mini Pocket Cable Tester is a small size tester that maps multiple locations of RJ45 network cables and detects short circuits, openings, faulty connections, inversions and split pairs.
This tool can be used with the integrated tone generator with four different tone combinations along with a tone probe to detect where a cable is routed and the location of the cable end.
You can determine the condition of the cable, if it is in good condition or defective, and shows it on your LCD screen. A set of five remote mapping controls is included to locate finished cables in wall outlets or patch panels. It also identifies the connection panel port where the network cable is terminated and can find and correct the position of exposed or hidden cables.
