Abstract
Precise null balancing technique has developed for 10-V Josephson junction array voltage standard system (10-V JJAVS). New technique is achieved by (1) precise capturing of the desired Josephson step, (2) millimeter-wave adjustment for making strict null balancing, (3) use of a stable chopper-type digital voltmeter (DVM) as a null detector.
