Mass Calibration with Robotic Mass Comparators

A robotic mass comparator is very productive, reliable and accurate piece of equipment which is used for the calibration of weights by national institutes, calibration laboratories and weights producers to calibrate all weight classes from the smallest available weight, starting from 0.05mg, up to 20kg. Performance and reliability on the one hand, productivity on the other, are of concern to metrologists. To meet their requirements, many factors have to be considered from the operator side as well as from the manufacturer side. This paper gives an overview of robotic systems, the ideal operation and the relevant factors which have to be taken into consideration.
