Claims

[Scope of utility model registration request]

a detection means for detecting a physical quantity accompanying deformation of the specimen loaded by the loading means; a setting signal generating means for generating a setting signal defining a pattern for loading the specimen; In a data sampling device of a materials testing machine, the data of the physical quantity is collected, the data sampling device of the material testing machine comprising a control means for controlling the load means so that the load means is input, and a data sampling means for sampling data from the detection signal at a timing when a timing signal is input. a phase difference calculating means for calculating a phase difference between the setting signal and the detection signal sampled in synchronization with the timing signal before the timing signal; and a delay means for delaying the timing of the timing signal by the phase difference; A data sampling device for a material testing machine, wherein the data sampling means collects data of the physical quantity in synchronization with a delayed timing signal.
