一、前言 WZY-200型洛氏硬度计测量机构误差校准仪(简称校准仪),是校准、检测洛氏硬度计测量机构误差的专用仪器,它可以校验洛氏硬度计测量机构进、回程各分段及全程的误差。按标准洛氏硬度试验法设计的工作硬度计,其硬度示值是以压痕深度差来计量的。硬度示值一般采用机械杠杆系统放大后,由指示器直接示出。所以测量机构误差的大小是关系到硬度计示值正确与否的关键问题之一。测量机构误差是大是小,是否在
I. Preface WZY-200 Rockwell hardness measuring mechanism error calibrator (referred to as the calibrator) is a special instrument for the calibration and detection of Rockwell hardness measuring mechanism, which can check the Rockwell hardness measuring mechanism into and back The sub-paragraph and the entire error. According to the standard Rockwell hardness test designed hardness tester, the hardness value is based on indentation depth to measure. Hardness indication generally use mechanical lever system to enlarge, the indicator shows directly. Therefore, the size of the measuring mechanism is related to the hardness of the correct value of one of the key issues. Measuring mechanism error is big is small, is it right?
