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