  • Abstract
    The METAS watt balance project has been in operation for 10 years. After different improvements and modifications, the present setup allows a reproducibility for a two weeks measurement series of 0.05 × 10-6 W/W. The analysis of several measurement campaigns is underway to produce a value of the Planck´s constant h in the near future.
