Abstract :
A new type of moving-coil watt balance is under construction at the Swiss Federal Office of Metrology (OFMET). The aim of the experiment is the monitoring of the kilogram by means of the electrical standards with a relative uncertainty of /spl les/10/sup -8/. The paper presents the main features of the proposed instrument.
