A method has been developed for the adjustment of the results of measurements of length during calibration of a field comparator for verification (calibration) of distance meters and distance metric parts of total stations. The method of processing the results of comparisons of distance meters to the field comparator using the least squares method (LSM) was also developed on its basis. The additive biases of length measurements by each distance meter are evaluated according to the LSM, as well as the biases that are entered to the results of length measurements by each reflector. Multiplicative degrees of equivalence of the distance meters are also calculated. During calibrations of field comparators, the biases and degrees of equivalence, obtained during the comparisons of distance meters, should be used as corrections. According to the LSM, the uncertainty is evaluated by type A of the value of the length of the field comparator lines, as well as the biases of measurements by distance meters.
