- Abstract:
- Surface plates are used in the industry and measurement laboratories for performing measurements of length, angles and deviations of form and position of measured subjects, for checking and control of measurement bars and rulers. Our aim is to perform a calibration of the surface plate without involving either interferometric system or autocollimator, which would be too expensive, therefore using only electronic levels. And even when the appropriate device for calibration is chosen, the decision between many different types of algorithms has to be made. On top of all, traceability of measurement must be also assured. Research work in this field, represented in this article, is focused mainly on assuring the calibration traceability of results when performing measurements of flatness with electronic levels. Traceability is assured with accurate sine bar SL001, developed in our laboratory especially for purposes of very precise calibrations.
