For good foil shielding, you should be reading one or two ohms at most. My experience is that if sections aren't properly connecting, then I get 'overload' indication on even the high ohm settings on the multimeter, showing no connection at all. Beeping is an indication of good continuity, so I wouldn't worry too much about sections that beep.
The other thing to check is that the foil has a good connection to ground. It should be connected to ground by the pots on the pickguard touching the foil there, and the foil on the pickguard making contact to the foil in the cavities by contact pressure with the pickguard on. Which is why I like as much overlap on the body and pickguard of foil as possible, and use all the space under the pickguard. But worth checking for a connection from the back of the pots to the foil on the pickguard, just in case the pots have some form of insulation preventing a through connection (unlikely but better safe than sorry).
