Mass dissemination using a fully automated mass comparator robot system

Abstract:
We used a new mass comparator robot system which covers 6 decades from 1kg down to 1mg in a single system to calibrate an entire 1kg-1mg OIML (5, 2, 2*, 1) weight set against one 1kg reference by subdivision in less than 1.5 days using a fully automatic robot system with no operator action except loading the magazine at begin.
Due to the possibility to perform subdivision comparisons of one weight against combinations of up to four other weights we don’t need the "5" check standards. We use one additional "1" check standard and 8 equations for the 5 unknown in each decade. The mean values of the weighing differences of 6 ABBA cycles are used for the adjustment calculation. A detailed description of the weighing design and the adjustment calculation is given.
