ABSTRACT:
An uniformly-graduated arcuate dial of a pressure gauge is mounted with play and fixed in a position to compensate for any deviation from a linear graphical relationship of the angular displacement of a pointer as a function of the pressure, by setting three graduations of the dial along three reference lines coinciding with the positions of the pointer at three corresponding reference pressures.
