Abstract :
Summary form only given, as follows.Random uncertainty of 0.08 /spl mu/W/W in the NIST watt balance has been achieved by improvements in a velocity measurement using three laser interferometers and by the reduction of filter delays and electrical noise. The latest results of this experiment are presented.
