Abstract
The disclosure provides a tensile testing machine and includes: a processing filter that removes a noise component included in a test force measurement signal output from a load cell; and an adjustment unit that adjusts a frequency characteristic of the processing filter. The adjustment unit receives a detection signal output from the sensor, and adjusts the frequency characteristic of the processing filter on a basis of a difference between output signals of two low-pass filters having different frequency characteristics.
Claims7
A material testing machine comprising:
- a processing filter that removes a noise component included in a detection signal output from a sensor;
- and
- an adjustment unit that adjusts a frequency characteristic of the processing filter,
- wherein the adjustment unit receives the detection signal output from the sensor, and adjusts the frequency characteristic of the processing filter on a basis of a difference between output signals of two low-pass filters having different frequency characteristics and serving as the processing filter.
A control method of a material testing machine which includes a processing filter of removing a noise component included in a detection signal output from a sensor, the control method comprising:
- receiving the detection signal output from the sensor;
- adjusting a frequency characteristic of the processing filter on a basis of a difference between output signals of two low-pass filters having different frequency characteristics and serving as the processing filter.
