Know your gear
Identify unknown telephone and network connections instantly. Identifies the type of circuit before connecting and possibly damaging equipment. Also identifies the type of equipment attached at the far end and to warn of the presence of potentially harmful signals. This tester is also great for when you're updating your cabling plant information or verifying functionality. Features 6" (15.2-cm) pigtail. If you have a wall connection turned on its side or placed upside down you can still plug in the tester and flip it over to get the reading. A ferrule at the base of the pigtail protects the tester from breakage and excessive cable bends.
