A little more info on what I plan to use the MM for - I left all of this out, since I figured it would be a bit laborious to go into the details. They are needed, so I should have included them. In addition to general, around-the-house uses, I would like to buy various electronic kits to build with my daughter. Things like radios, transmitter, etc. I would need to be able to test circuits, components and of course, batteries.
The thermocouple would be used for various things, but would also be used to test brew temperatures for coffee machines.
The AC testing I would need would not be real high voltage, nor anything complex. Just house current, possibly 220 at times, test sockets, switches, outlets, etc.
I have no plans to test multiphase industrial AC motors, generators or other commercial applications.
