Abstract
A compact ac-dc transfer standard system has been developed at AIST. The system is able to perform both ac-dc difference measurements and fast-reversed dc (FRDC) measurements, at voltages from 1V to 10 V. A remote-calibration capability is realized using a digital-output thermal converter as a travelling standard. The system has the capability of calibrating ac-dc transfer instruments with an uncertainty at a 10-6 level, and thus can be used as a primary ac-dc transfer standard in calibration laboratories
