The performance of the KIBB-g1 tabletop Kibble balance at NIST

摘要

A tabletop-sized Kibble balance (KIBB-g1) designed to directly realize mass at the gram-level range with uncertainties on the order of parts in 10(6) has been developed at the National Institute of Standards and Technology (NIST). The masses of a nominally 5 g and 1 g weight were determined with standard uncertainties of 9.0 g and 6.7 g, respectively. The corresponding relative uncertainties are and . The construction of the instrument, capabilities, and full uncertainty budgets are presented in this manuscript.
