Abstract
An improved scale, including bathroom-type scales, is provided by employing markings on the dial for calibrating the scale using photosensor equipment. The adjusting nut of the scale and the calibration stud of the scale are both accessible for automated mechanical calibration after assembly of the scale. As a result, an iterative calibration procedure is employed by machine as opposed to traditional manual methods. Photosensors read the dial and send a signal to mechanical driver or wrench mechanisms for automated calibration. The improved scale and calibration method reduces labor and production costs.
