If test patch panels or wall plate outlels, two cables which can match each other (RJ45) be connected to the tester. If several cables are not connected, several lights not turn on respectively. If less than two cables are conntected, none of the lights is on. If two ends of a cable is disordered, for example NO. 2and NO. 4, then displays on: Main tester: -4-5-6-7-8-G; Remote tester: 1-4-3-2-5-6-7-8-G If two cables are short circuited, neither of the corresponding lights is on of the remote tester while main tester remains unchanged. If three cables, including three, are short circuited, none of the corresponding liaghts is on. If test cables of the same axes, BNC turns on when the cable works., Weight: 0.25463391261 pounds, Manufacturer: Awwertse
