Abstract :
The Swiss Federal Office of Metrology and Accreditation (METAS) has been continuing to work toward a 100-g watt balance apparatus with an uncertainty of 1 ×10-8 W/W. Currently the experiment is producing preliminary measurements reproducible at the 1 ×10-6 W/W level. Our progress, measurements, and plans for the future are presented.
