Abstract

Precision measurement is one of the important goals of measurement and calibration. Positive measures are designed to provide researches with the highest accuracy and precision levels. In force measurements, force measuring instrument manufacturers are striving to achieve the best force measurement resolution to accompany the high level of calibration measurement capabilities achieved by the primary deadweight machines. In the calibration of the force transducers, polynomial equations which correlate, the applied load on the transducer and its corresponding output signal in mV/V are deduced. These equations contain numerical constants A, B and C. This paper introduces a mechanism to determine the suitable number of significant digits for these constants. Error analysis procedure for the calibration polynomial equation is proposed. This proposed algorithm safeguards the most accurate and realistic method for rounding the calibration constants
