ABSTRACT:
The invention relates to a method to calculate optimum wicket gate positions based on only the initial face-to-face readings comprising the steps of measuring the initial gate openings, determining an optimum unit opening, and rotating each gate to the optimum opening. The method results in a one time adjustment that is more accurate and faster than conventional methods.
