AD584 voltage reference and new meters.

re-upload of the original video which somehow disappeared in YouTube abyss. In this video I test my old and new meters using two voltage reference boards with AD584 chips. To my surprise, the cheapest of the three meters tested is the most accurate in these measurements.
