Evaluation of standard uncertainty of measured mass difference on 10 kg comparator balance

Abstract

Three pairs of different weight support plates, which are needed in the procedure of multiplication of 1 kg value, were used on Sartorius C10000S comparator balance in order to study their influence to the measurement results. In the study a pair of 2 kg weights was compared with the aid of different support plates. The mean values and the standard deviations of the measurements with the support plates were compared to the results of measurements without the use of the support plates. The analysis confirmed the differences in the means and in the standard deviations of measured results when various support plates were used but in a smaller extent as it had been noted in earlier routine measurements. The analysis showed that the use of a certain pair of the plates assured smaller standard deviations and better agreement with the results of measurements where the plates were not used.
