For testing of the geodetic angle measuring instruments, such as theodolites and tacheometers widely implemented in construction engineering, other measuring instruments and devices are used. The errors of these instrumentand devic-es must be also determined and evaluated. Evaluation of the influence of various features of the instruments on the accuracy of measurements allows to eliminate the determined errors or at least to reduce theirinfluence. Such evalua-tion is especially important in the case of precise measurements. However it is also a very complicated task due to the lack of references of the high enough accuracy. In this paper a principle of determination of the influence of angle measuring instruments, such as autocollimators, mirrors and turn tables (used for testing of geodetic instruments), on the accuracy of angle measurements by means of correlation analysis with some practical tests is presented.
