Abstract
A method for calibrating an electronic scale includes sampling the output of the scale a predetermined number of times to generate a number of average readings for the weight that is placed on the scale, comparing two successive average readings and selecting the average reading that is within a predetermined weight of the previous average reading, comparing the digital signals sampled representing the selected average reading with the setting of a plurality of settable switches in which each switch position will represent a binary bit and displaying on a display the switch settings which represents the selected average reading of the output of the scale. The operator in response to instructions displayed on the display will place a weighted object on the scale, set one of the switches of the settable switches in response to placing the weight on the scale and set the switches in response to the instructions displayed on the display to store the selected average reading in the settable switches. The method is repeated for a second weight.
