A contribution in replacing the kilogram by means of the voltage balance ETF

This paper gives a short description of the basic principle of work of the EFT voltage balances, as well as the measurement procedures enabling the absolute determination of the volt. Recapitulation of the previous achieved measurement results and the estimation of expected uncertainties for the further experiments using the so-called charge-method, is also given. New measurement series have successfully started at the end of 1993.<
