摘要
数显弧度规用于圆弧尺寸的快速测量,精度比半径样板高。本文重点分析了仪器的结构、原理及机械误差,确定了计量性能及校准项目,并研究了相应的量值溯源方法,为校准工作提供了技术参考。
The digital display radian gauge is used for rapid measurement of arc size, the accuracy is higher than the radius template. The thesis focuses on the structure, principle and mechanical error of the instrument, deter- mines the measurement performance and calibration items, and studies the corresponding measure value traceability method, which provides a technical reference for the calibration work.
