[Test-Equipment] Bench meter recommendation?

Brian,
Thanks for your reply.

Well, boat anchors probably not. Solid state is probably more my 
focus. And my comment about a "standard" was ill-conceived, agreed. 
Simply to have a meter on the bench that -- as you point out -- 
probably will stay there and not be knocked around, would give me 
something to reference my others to, once it has been ref'd itself. 
But maybe it's best to leave standards and such out of the formula 
for now, and after I've acquired a meter, then I can ask questions 
down that road...

So maybe that gives more useful information?

Thanks again,
Dave
