Abstract
The National Institute of Standards and Technology (NIST) has rebuilt the apparatus and facilities for the watt balance experiment. The goal is to electronically monitor the SI kilogram at an uncertainty of 10 nW/W. We discuss the design changes and available test results to illustrate the improvements of the system.
