How to improve the data accuracy of electronic universal testing machines

Electronic universal testing machineHow to improve the accuracy of data? In addition to paying attention to the daily maintenance of the electronic universal testing machine, we should also regularly check other aspects of the universal testing machine. If we encounter a large deviation in the test data, we should first check and exclude the following situations to improve the data accuracy of the electronic universal test machine:
1. The test speed of the electronic universal testing machine is not standard during the testing process. Too fast or too slow will lead to different test results.
2. Whether the sample is clamped correctly during the test of the universal testing machine, and incorrect support will affect the accuracy of the test results.
3. Whether there is a zeroing operation before the test machine is tested, and the test starts if it does not return to zero. The results of the test will definitely be inaccurate.
4. Is the force sensor damaged when it is impacted by external force or used in excess capacity? The damage to the sensor will affect the data.
5. After the sensor is used for a certain period of time, the strain undergoes elastic flexural transformation and does not return. In fact, this strain deformation is very small. It is recommended that the coefficient of the force sensor should be recalibrated in one year and the data should be corrected.http://www.hssdtest.com/
