A device for measuring force of bending of a head-flexure assembly by a given amount characterized by the distance between a clamping surface for one end of the flexure and the plane (recording surface) in contact with the head at at the other end of the flexure. The device includes a load cell with a cell reference surface adjustably supported on a cell base which is slidably mounted on a main base. Adjustment of the location of the cell reference surface with respect to the clamp surface is achieved by a shaft threaded into the load cell with a first thread and threaded into the main base with a second thread so that by turning the shaft, the distance between the two reference surfaces can be very accurately adjusted. When the load cell is deformed by application of the head loading force to the cell reference surface, a signal from the load cell actuates a mechanism maintaining the cell reference surface in its initial location thereby maintaining the initial flexion of the flexure.
