Circuit Specialists has meters and they throw in a free gift for
over $50. Or Fry's retail this weekend. B&K is an OK economy
brand available at both places. The cheap analog meter might cause
you problems down the road with sensitive components on the
resistance scale, so keep it for analog peaking of small voltages.
Actually, my "cheap" analog meter did come from Circuit Specialists!
I got it free when I bought my oscilloscope.
Having now measured my bench power supply (not my precious K2!) with
just about everything I own that measures voltage, I'm inclined to
believe that the Circuit Specialists freebie DMM is telling the
truth; it matches the meter built into the bench power supply. My
other tiny pocket-size DMM measures about a tenth of a volt higher,
and my analog meter from when I was nine measures about a tenth of a
volt lower and hasn't been calibrated since about 1977.
So at the moment, I'm going to accept the freebie DMM's results...
unless somebody knows how many voltmeters it takes to establish a
quorum... :-)
But I'm still thinking that, sooner or later, it would be nice to
have a "nice" meter... so again, if anyone can recommend one that
isn't *too* expensive; I'd be interested to hear. Maybe a bench meter
rather than a handheld? $100 to $200ish? And maybe something from
Circuit Specialists, because, you know, if I spent more than $50 on
my meter, I could get another meter for free! Maybe that would would
constitute a quorum? :-)

Well, I searched around a bit and found *another* cheap DMM, which
seels to be reading about 0.12 to 0.14 volts higher than the first
one. Now I don't know which one to believe! :-)

Now I need to find my *other* other meter, the analog one I got
when I
was nine years old, and see what it thinks...

Hi and welcome!
It doesn't happen too often, but have you checked the accuracy
of your
"cheap" DMM? If you don't have anything to compare it with, you
can get an
idea of its condition by measuring the voltage across a fresh
alkaline
battery. It should read about 1.57 and 1.58 VDC.
