Abstract
The method of calibration of scales with an irregular structure typical for absolute angle encoders based on pseudo-random codes has been developed and tested. The calibration results at a level of ±2.2ʺ with an uncertainty of ±0.5ʺ, characteristic for the measuring and diagnostic unit AE.1686 used, are experimentally obtained. The reliability of the results of calibration of irregular scales is confirmed by the identity of the curves obtained when comparing them with the calibration curve of a regular scale formed at another radius in a single technological cycle together with one of the controlled irregular scales.
