Claims

[Scope of utility model registration request]

In a strength testing machine that is equipped with a command value generation device that increases the command value indicating the load to be applied to the specimen approximately linearly with time, and applies the load to the specimen according to the command value from the device, the measurement mode, the above command value is increased by increment △C at approximately constant time intervals.
a first command value generating means that generates the command value in increments;
a deviation calculation means for calculating the deviation between the target response value and the actual response value of the specimen each time the first command value generation means generates the command value a predetermined number of times; , the above increment △C
a correction data calculating means for calculating a correction increment ΔS for correcting the deviation and instructing a correction mode; A second command value generating means generates the command value by increasing the sum of the increment ΔC and the modified increment ΔS by ΔC+ΔS, and every time the second command value generating means generates the command value a predetermined number of times, 1. A command value generation device comprising: means for instructing a measurement mode.
