PROBLEM TO BE SOLVED: To solve a problem that time during which a measurement value is obtained has prescribed delay time due to a plurality of delay elements when filter processing is digitally applied to output obtained from a sensor for detecting characteristics of a test piece. SOLUTION: Feed back control of test force is rapidly executed, by defining that estimated test forceαin the present time corresponds with an externally dividing pointαcalculated by externally dividing a line segmentγβat the ratio of 3:1 when average test force calculated by averaging sample data from the present time (a) to the past time (b) is defined asβand average test force calculated by averaging sample data from the past time (b) to the past time (c) is defined asγ.
