ABSTRACT:
A calibration method for a potentiometer which provides indicia reflecting an accurate indication of actual electrical resistance throughout the resistive range of a particular potentiometer. The indicia includes a number of graduation marks or symbols having a range and spacing unique to the resistive characteristics of the particular potentiometer. The indicia is fixed with respect to a known location associated with the particular potentiometer. The range and spacing of the indicia graduations is derived from measured resistance values at predetermined locations along the resistive member of the particular potentiometer.
