AB  - The results of experimental measurements with use of a electronic tacheometer (total station) proving
the presence of elastic deformations of the device support caused by imbalance of the moving parts (the
alidade). Deformations lead to errors in a measurement of horizontal angles. The study presents the research
methods of the fixed part of a electronic tacheometer as well as ways to increase in several times the accuracy
of determining the azimuth and vertical deformation of the support. For measurements use a special device with
two optical mirrors located vertically at an angle of 90° to each other and fixed to the stationary part of the
electronic tacheometer below the alidade but above the support. If there are no elastic deformations, then upon
rotating the alidade of the horizontal circle of the tested electronic tacheometer, the device must be static. If
elastic deformations exist, the device with mirrors may turn around the vertical axis (azimuthal rotations) that
can be registered by other electronic tacheometers (measuring tacheometers). These turns lead to errors in
measuring horizontal angles.
