Abstract

There is provided a material testing machine that a control device of the material testing machine includes a detection circuit which extracts a resistance component caused by the physical quantity and a capacitive component caused by an electrostatic capacitance of the cable from a measurement signal from the detector, a memory element which stores a normal capacitive component extracted by the detection circuit, and a comparator which compares the current capacitive component extracted by the detection circuit with the normal capacitive component, and when a comparison result from the comparator indicates that a value of the current capacitive component varies beyond a predetermined allowable range with respect to the normal capacitive component, it is treated that the cable is disconnected, and a disconnection warning is provided.
