How to operate the spring tensile testing machine?

The operation steps of the spring tensile testing machine are as follows: 1. Before the test, check whether the power supply of the testing machine is connected correctly and ensure that the power supply voltage is consistent with the rated voltage of the testing machine. 2. Choose the appropriate test method and test fixture according to the characteristics and requirements of the test materials. 3. Clamp the sample on the testing machine to ensure that the clamp is firm and will not slip. 4. According to the requirements of the test standard or test method, set the parameters of the test machine, such as tensile speed, stress, strain, etc. 5. Start the testing machine and start the tensile test. During the test, the changes of the sample should be observed and the experimental data should be recorded. 6. After the test, turn off the test machine, take out the sample, process and analyze the test data, and get the test results.It should be noted that you should be careful when operating the testing machine to avoid misoperation or improper use. At the same time, you should pay attention to safety and wear necessary protective measures to avoid accidental injuries during the test.
