A couple of general questions to the reflector regarding voltage meter
calibration:
1) if the meter is spot-on on one scale, can one assume it is so on all
scales (or all autoranges)? I suspect the answer is no, but am surely
willing to hear the word of those who know.
2) if the meter reads
Well, I received my 5 volt calibration standard from Joe Geller at
gellerlabs.com today.
I upgraded to the KQ chip. The papers with it shows that it is calibrated
to +/- 10 microvolts. On a 5 volt scale, that is +/- 2ppm. The initial
calibration is then +/- 0.0002%!
I connected it to my A

Look on my website www.qsl.net/w3fpr for an easy to build calibrator for
your DMM.

I looked at Don's neat little project, and really like it.
However, I just don't have time to scratch-build right now.
Out of curiosity, I did an EBay search for "voltage reference standard" and
Don:
That is really cool. I'm definitely figuring to build one of those.
