5. features of test software

5.1. Automatic stop: After the sample is broken, the moving beam stops automatically;

5.2. Condition storage: The test control data and sample conditions can be made into modules, which facilitates the batch test;

5.3. Automatic speed change: The speed of the moving beam during the test can be changed automatically according to the preset program or manually;

5.4. Automatic calibration: the system can automatically realize the calibration of the indication accuracy;

5.5. Automatic save: After the test is over, the test data and curves are automatically saved;

5.6. Process realization: the test process, measurement, display and analysis are all completed by the microcomputer;

5.7. Batch test: for samples with the same parameters, it can be completed in sequence after one setting

5.8. Test software: WINDOWS interface, menu prompt, mouse operation;

5.9. Display mode: data and curves are dynamically displayed with the test process;

5.10. Curve traversal: After the test is completed, the curve can be re-analyzed, and the test data corresponding to any point on the curve can be found with the mouse;

5.11. Curve selection: Stress-strain, force-displacement, force-time, displacement-time and other curves can be selected for display and printing as required;

12. Test report: The report can be prepared and printed according to the format required by the user;

5.13. Limit protection: with two levels of program control and mechanical limit protection;

5.14. Overload protection: when the load exceeds 3-5% of the maximum value of each gear, it will automatically stop;

5.15. The test results are obtained in two modes, automatic and manual, and reports are automatically formed, which makes the data analysis process simple.
