FIELD: instrument making.
SUBSTANCE: several measuring instruments are used for measurement of the required value and one summation measuring instrument is used for measurement of the value which shall compose the sum of the above values. Measurement results of measuring instruments and summation measuring instrument are recorded for many times in summation measuring instrument. On the basis of analysis of the recorded measurement results and their recording time there formed is model of relative measurement error of individual measuring instruments and deviation of measurement error of individual measuring instruments. At that, summation measuring instrument has accuracy class which is higher than that of measuring instruments.
EFFECT: accuracy improvement.
