Force Transducers Relative error of Zero

Abstract

This study represent the influence of relative zero error on force proving instruments classification. It is directed to compare the relative zero error resulted from the three loading scenarios applied during calibration of force proving instruments in increasing and decreasing scheme as per ISO 376:2011. It is conclude that the maximum relative zero error resulted after the first loading series at zero position. Two methods are recommended to be proposed as a unique method to calculate the maximum relative error of zero from the first and second loading series or from the preloading series
