Measurement method of detection accuracy in material tester and material tester

摘要

PROBLEM TO BE SOLVED: To provide a material testing machine and a method for measuring detection accuracy in a material testing machine, which can easily measure the detection accuracy of a material testing machine without using a detection loop, a weight or the like. SOLUTION: A control unit 40 stores as first data the relationship between a distance between a table and a crosshead measured in a state where a normal material test can be performed and a force detected by a load cell 16 at that time. , The storage unit 41 that stores the relationship between the distance between the table and the crosshead measured before the material test and the force detected by the load cell 16 at that time as second data, and the storage unit 41 are stored. A comparison unit 42 that compares the first data and the second data, and a warning display unit 43 that displays a warning based on the comparison result between the first data and the second data compared by the comparison unit 42. To be equipped. [Selection diagram] Fig. 2
