It is for finding continuous flow in wiring if your not sure which wire goes where. This is a video I used to help me to figure out a 4 way switch setup. http://www.thisoldhouse.com/toh/tv/ask-toh/video/0,,20785338,00.htmlHope it helps. **Q: Hooking tester in panel box is a probl locating grnd and neg. Can you attach rem to grounding bar to test for neg and grounding wire continuity?** A: You can test everything you want as long as the object that you want to test is de-energized **Q: do the units require any kind of recalibration or servicing to ensure it is still working correctly** A: No, none that I know of. It works fine and comes with instructions. It saves a lot of time and trouble, especially if you are working alone. ## Frequently Bought Together - Extech CT20 Remote and Local Continuity Tester - Southwire Tester; Continuity PRO 40040S - Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories, 2-Piece Set, Includes Cat.
