Pinch grip dynamometer field testing calibration stand

摘要

A pinch grip dynamometer field testing calibration stand for a pinch or finger grip dynamometer having a base defined by a platform and a vertical post, a dynamometer holder attached to the platform, and upper and lower calibration plates slidable on the post. The dynamometer is supported by the holder with its load application point (a concave groove in the case of a mechanical dynamometer, or the concave face of a button in the case of a hydraulic dynamometer) in proximity to the post. The bottom surface of the lower calibration plate has a convex protrusion which applies a load to the dynamometer. The load is supplied by calibrated weights of known mass supported in a groove on the top surface of the lower calibration plate, and by a groove in the bottom surface of the upper calibration plate when the weight needs support for its upper portion.
