Using REF200 As 100uA Precision Reference

A few weeks ago, I discussed how to calibrate middle to low end DMMs using a precision voltage reference such as REF01. Of course, you can perform similar calibrations using a precision current reference as well. And in many cases using a precision current reference is a better choice as it can be used to generate voltage references as well using precision resistors.
