In the paper the methodological problems of the measuring instrument calibration are presented. The key problems are connected with the choice of the form of calibration curve, and the methods of data processing. Two main cases are considered. The first one is when the least squares method is applicable. The second case is when this method is inconsistent, so the various confluent methods should be applied. The efficiency of method is described by the bias and second central moment of estimate. These problems and methods are specified for the particular case of linear calibration curve.
