Abstract

The project, the Electronic Realization of the Kilogram, has rebuilt the NIST Watt balance, which has been fully operational for nine months. Short-term noise is at an all time low with overnight runs exhibiting standard deviations of parts in 108. Recent improvements are discussed that have led to this enhanced performance, as are several significant error tests. Present results are now within 1 ?W/W of previously reported values, but error checking to report a more precise value has not been completed.
