CA 2181370

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.

Procédé d'étalonnage d'un potentiomètre produisant un repère reflétant une indication exacte de la résistance électrique réelle, sur toute sa plage de fonctionnement. Le repère comporte plusieurs marques ou symboles de graduation dont l'étendue et l'espacement sont spécifiques aux caractéristiques de résistance du potentiomètre. Le repère est fixé par rapport à un emplacement connu associé au potentiomètre concerné. L'étendue et l'espacement des graduations sont fonction de valeurs de la résistance mesurées en des points prédéterminés situés le long de l'élément résistant du potentiomètre considéré.
