After a brief introduction devoted to fundamentals of representation theory
of measurement, explanation is focused on units of measurable quantities and
possibilities of their definition, realisation, conservation and
reproduction by means of measurement standards. Main attention is paid to
measurement methods and to techniques of evaluating and increasing
measurement accuracy. Fundamental problems of theory of measurement errors
and uncertainties are outlined and basic principles of design of experiments are discussed.
