ABSTRACT:
A top loading load cell mass comparator having a load cell and a cantilevered beam connected between the load cell and a weight supporting platform which is self-centering to compensate for off-center loading when moving or replacing weights on the platform. A preload compressive force is applied to the load cell to minimize hysterisis and creep error in the load cell during weight exchanges on the weight supporting platform.
