Can this device be used to test the continuity of a single conductor wire instead of a conductor pair?

I wondered about that too so I asked my son in law he's an electrician according to him you can't do it remotely but it can be done without the remote option as long as you can get to both ends of the single wire which makes this device useless in most cases because most of the wires I would want to remotely test are single wire

how many feet can be tested at one time ?

Not sure what your asking about how many feet? 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.

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?

You can test everything you want as long as the object that you want to test is de-energized

do the units require any kind of recalibration or servicing to ensure it is still working correctly

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.
