Abstract: Calibration method for volumetric blending especially adapted to calibrate the volumetric blending equipment according to the movement of the dispensing mechanism relative to the volumetric units dispensed. The method broadly includes the steps of initiating the movement of a dispensing mechanism, counting a predetermined number of volumetric units as the dispensing mechanism moves, measuring and recording the quantity of the ingredient dispensed for predetermined unit count of said dispensing mechanism and then calculating a calibration ratio of ingredient quantity to movement of the dispensing mechanism. The calibration ratio remains constant for the ingredient dispensed and regardless of the speed of the dispensing mechanism.
