why don't you get a secondhand Fluke 77 series DMM or even a 87III or 87 from eBay or so on
I see them all the time on there - I even went through a phase of buying one a week for a while.
they cost less than $50 and are way more reliable than anything else you'd get.
just don't bother with the cheap brands - they aren't reliable, they drift, they fall apart, they aren't safe and it's just a needless expense in the long term when it falls apart. a 77 series secondhand will cost less than $50 and probably last forever
people will say that sub $50 cheapie DMMs are fine but they really aren't.
plus the Flukes Autorange and have the hold functions which are unbelievably useful
