FIELD: physics.
SUBSTANCE: verifying and calibrating device for vertical angular surveying measuring systems contains foundation platform with mounted table with fixed tested device. Vertical channel bar with travelling carriage stand and plate is arranged on the isolated foundation. Stand contains rigidly fixed raster measure mount, while the carriage includes reading head. The plate accommodates the level, split four-bench diode unit and corner reflector rigidly fixed at the level of split diode and lens objective on the level case. The carriage is provided with microsupply lead screw, balancing arm, guides and output terminal. Horizontal surface of the foundation includes oscilloscope, screen, power unit and electronic counter, while the lower and upper parts of the channel bar contain fixed supporting arms of measuring systems.
EFFECT: higher accuracy and stability of measuring system testing for cyclic interpolation error.
