Monitoring the errors of angular-displacement converters with automatic correction of the results of the measurements

This paper discusses a method of experimentally studying a prototype of a test stand (goniometer) for monitoring the accuracy of angular-displacement converters with automatic correction of the errors of devices for matching a reference converter with the converter being monitored and the results of experimental studies of this prototype. A description is given of matching devices that allow the housing of the converter being monitored to possess all degrees of mobility except for rotation around the axis of its shaft (rotor) during measurements.
