Rob:

If you are suggesting using a digital meter for resistors,
wouldn't it be best to use a digital meter for voltages as well?

Let him bring his legacy device up to snuff so he can do all
of the things it once did.

He probably has a digital meter already.

>> I acquired at a local hamfest last weekend a BEAUTIFUL heathkit IM-11 VTVM. It works well on ac and dc scales but would not calibrate on Ohms.   Looking at the back I noticed discoloring around the screw that holds the C Cell battery spring so I knew what I would find when I cracked it open, and oh yes.. a melted D Cell battery.
