Introduction to the parameters of universal testing machine

Universal testing machineParameter description:

The deformation measurement index parameters include measurement range, display error, sensitivity, and resolution.

Measurement range - The range between the small size and size of the material or component that the test machine can measure through the measurement system.

The display value error - the difference between the measured value recorded or displayed by the sample deformation value and the actual value of the measured value is called the display value error of the test machine measurement system. The display error is inevitable, and its size is within a specific range or a specified range by a standard.

Testing machineDeformation measurement sensitivity - the displacement rate of the sensitivity indicator relative to the measured change. Sensitivity is a mark for measuring physical instruments. The more refined the sensitivity of the test machine measurement system, the higher the accuracy of the measurement result.

Testing machineThe resolution of deformation measurement refers to the measurable small accuracy of the measurement data of the photoelectric encoder of the test machine. The greater the resolution, the more accurate the measurement results.
