1. A method of characterizing a pressure sensor of a process device, comprising:

  • applying a plurality of pressures to a pressure sensor of the process device across a characterization pressure range; and

    receiving outputs from the pressure sensor related to the applied pressure;

    determining a compensation relationship based upon the outputs from the pressure sensor;

    wherein different applied pressures are non-uniformly distributed across the characterization pressure range.
