ABSTRACT:
A calibration-test member in the form of a ball plate fixedly mounts a plurality of precision balls arrayed in spaced relation in a single plane. The ball plate is of symmetrical construction with respect to this plane, the balls being so mounted within one or more cutouts of the plate or on the edge of the plate, with ball centers in the plane of symmetry of the plate, that contacting of the balls is possible from both sides.
