METROLOGICAL DEVICE FOR THE SQUARE STANDARDS CALIBRATION
J. Mokros, M. Hain
Abstract:
In this paper the principle and device NME 90° for large square standards calibration is described. The self-calibration methods of measurement are used. They allow very low uncertainty of the square calibration with mathematical elimination of measuring column straightness deviations. The process of measurement is full automated and controlled by PC, which collects and evaluates measured data. The uncertainties of the square measurement are also discussed in the paper.
