For current just compare to a known good meter. They are in series, right?
For voltage just compare to a known good meter. Use both series and
parallel here. It is a do-it-yourself hootenanny!
The accuracy you achieve will depend upon the standard meters you use. The
nice ones have those mirrored scales.
