摘要：A calibration fixture for a contact sensor for applying a uniform pressure toeach contact sensor intersection and a method of using the fixture. The fixture includes afirst plate against which a contact sensor is supported, a second plate confronting thefirst plate and spaced therefrom, an annular sealing member supported on the secondplate, a bladder disposed between the sealing member and the second plate to define afluid pressure chamber circumscribed by the sealing member, a frame for holding thefirst and second plates in their confronting relationship, and a pressurized fluid entrypassage extending through the second plate and communicating with the pressurechamber. The fixture is used by positioning a contact sensor between the first plate andthe bladder, then pressurizing the fluid pressure chamber by introducing pressurizedfluid thereinto to force the bladder into intimate contact with the contact sensor,uniformly to apply force against each electrode intersection circumscribed by the sealingmember, and then sensing the outputs for each electrode intersection.
