Which is why I finally decided to get out the soldering gun and put a 10.00 volt precision reference source in a mini Altoids tin, so there's no guessing, and I *know* when my meters are fibbing. The reference source is good beyond 4 digits, so when I hook it to a meter the meter had damn well say 10.00 or it gets re-educated, as the Chinese would say.
I'll be interested to see how the meters HOLD calibration, now that I've got a way to check on them.
My Fluke meters are all calibrated, my cheapies not so much, but I'd love to grab one of these chips. Got a link?????
