Abstract. A method for controlling the result of metrological evaluation of the instrumental error of meters of a single series according to the criterion of maximum likelihood is proposed. The problem of achieving the maximum likelihood of the result of metrological evaluation of the instrumental error of meters of a single series of certified batches consisting of the same number of devices is solved. It is shown that if, within each batch of instruments, the instrumental error is distributed according to the lognormal law, then when conducting certification serially for batches of meters, there is a certain ratio of the measured value, S.K.O. and the average value, when performing which the result of certification for the entire series of meters is considered the most plausible.
Keywords: error, likelihood, probability density, optimization, measurements.
