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.

Cette invention concerne une balance améliorée, y compris les pèse-personnes, par l'ajout de marques d'étalonnage sur le cadran scrutées par un dispositif à photodétecteurs. Le bouton et la vis de réglage de la balance sont disposées de manière à se prêter à une opération mécanisée d'étalonnage après assemblage. Cette disposition permet d'appliquer une procédure d'étalonnage itérative mécanisée par opposition aux techniques manuelles traditionnelles. Des photodétecteurs scrutent le cadran et envoient un signal de commande à un organe mécanique d'étalonnage, ce qui permet de réduire les coûts de main d'oeuvre et de production.
