Abstract :
A new versatile electronically coupled current comparator is presented in the paper. Its simpler design is more convenient for manufacturing yet it retains high accuracy in either manual or automated version. It provides a resolution of one part in 10/sup 6/ and has an estimated uncertainty less than 5/spl middot/10/sup -6/ in magnitude and less than 5 /spl mu/rad in phase at power frequencies.
