摘　　要：使用0.1级的力传感器对0.5级的电子万能材料试验机进行检定。在三段不同量程力值情况记录不同速度下使用连续加载方式和逐步加载方式的试验力示值误差,通过对示值误差的数据分析,得到测试速度对试验力示值误差的影响。Using class 0.1 force transducers to measure class 0.5 material testing machine. Recording the force error of indication by increasing the load step-by-step and increasing the toad continuously in different speed, Measurement results show that applying different test speeds and loading conditions during the verification of a material testing machine affects force error of indication results. In this study these results are discussed and the findings are presented.
