\n[\/vc_column_text][vc_separator][vc_column_text]Abstract: <\/strong>This work shows the results obtained by Inmetro\u2019s mass lab implementation of a simple Kibble balance approach for demonstration of its mass measurement principle based on the Planck\u2019s constant. It is based on some modifications of Mimimal Watt Balance work reducing the required electrical measurements by using two loudspeakers mechanically coupled so that one of them acts as a linear actuator in order to perform BL measurements in the moving phase. The mean BL value obtained in weighing phase was 2.66 N\/A and in moving phase 2.67 N\/A. The maximum error of mass values measured for standard weights in the range from 5 g to 50 g was lower than 5%.<\/p>\n
