Abstract: Embodiments of the invention generally relate to weighing scale diagnostic methods employing a comparison of like component operating parameters. In certain embodiments, weighing scale component output signals may be analyzed to calculate the difference between any two current weighing scale component operating parameter values, and the calculated difference may be compared against a maximum allowable difference for determining if a problem exists. Alternatively, a statistical analysis may be performed that considers the output signal of a given weighing scale component relative to the output signal of another weighing scale component or to the collective output signals of all of the other weighing scale components, and the comparison may be used to determine if a problem exists.

Abstract: Embodiments of the invention generally relate to weighing scale diagnostic methods employing a comparison of like component operating parameters. In certain embodiments, the difference between any two current operating parameter values may be compared against a maximum allowable difference, and/or the deviation of current operating parameters from a calculated measure of central tendency may be determined and compared against a maximum allowable deviation. Alternatively or additionally, a standard statistical test for outliers may be employed. An outlying difference or deviation may be indicative of a problem with the associated component. In other embodiments, the current operating parameters of like components may be compared against calibrated parameters and any deviation of the current parameter for a given component may be compared against the total deviation to determine the percentage of deviation attributable to that component.
