Abstract

An electronic scale performs a post-weighing calibration in which the user steps on the scale, and the scale provides an estimated weight based on the scale's stored tare weight determined after the previous weighing performed by the scale. The person steps off of the scale while the estimated weight is displayed, and the scale automatically performs the calibration process to determine the scale's tare weight and verifies the weight. The estimated weight is shown with an orange ellipsis, and the verified weight is shown with a green checkmark. The scale compares the stored tare weight with the new tare weight, and if the difference between the stored tare weight and the new tare weight is within a variation threshold, the scale identifies the weight as being verified. If the difference exceeds the variation threshold, the scale recalculates the weight, displays the corrected weight, and produces a tone as an alert.
