Abstract

La prsente invención se refiere a un método para corregir la salida de una escala de pesada para el efecto de histérisis, que ocurre entre la carga mínima y máxima aplicada a ella, con una historia de progresión de carga dada, caracterizado porque comprende los pasos de: derivar una expresión polinomial que representa los valores característicos de linealidad creciente de la escala, que se extiende desde la carga mínima hasta la carga máxima; derivar una expresión polinomial que represente los valores característicos de linealidad decreciente de la escala, que se extiende desde la carga máxima hasta la carga mínima; proveer una expresión de correción que represente una compensación de una de las expresiones polinomiales; obtener una representación del valor R, de una carga aplicada a la escala; derivar un valor de correción, como una aplicación del valor R, a la expresión de correción; ajustar el valor R, mediante la cantidad del valor de correción; y dar salida al valor ajustado.
