As a commonly used experimental testing instrument, the tensile testing machine is widely used in various industries and becomes an instrument with a very large base. However, as long as it is mechanical, various problems or mistakes will occur during use. For example, when the tensile testing machine is in use, a common problem occurs; the measurement data is inaccurate or the measured value is too large. What should we do when we encounter such a problem?
1. When the tensile testing machine is tested, the instrument is not initialized and the data is not returned to zero, resulting in inaccurate test data.
2. The long-term use of the sensor will occur elastically and will not return. Although this deformation is very small, it will still affect the experimental results. Therefore, it is necessary to recalibrate the coefficient of the force sensor in one year. The data is corrected.
3. The sample is not clamped positive during the test, and the test result will be inaccurate.
4. The test speed is not standard during the test. Too fast or too slow will result in different test results.
5. The force sensor is damaged by external impact or over-capacity use.
Through the above introduction, I hope that everyone has a general understanding of such issues, and try to avoid such problems in daily use.
