2.2.5 Conditional storage: The experimental control data and sample conditions can be made into modules, which facilitates batch testing; 

2.2.6 Automatic transmission: During the test, the speed of moving the crossbeam can be automatically changed according to the pre-set program or manually changed;

2.2.7 Automatic calibration: The system can automatically calibrate the accuracy of the displayed values; 

2.2.8 Automatic saving: After the experiment is completed, the test data and curves are automatically saved; 

2.2.9 Process implementation: The experimental process, measurement, display, and analysis are all completed by a microcomputer; 

2.2.10 Batch testing: For samples with the same parameters, they can be set once and completed sequentially;

2.3 software: 

This measurement and control software is used for microcomputer controlled electronic universal testing machines to conduct various metal and non-metal (such as artificial boards, etc.) tests. It completes various functions such as real-time measurement and display, real-time control and data processing, result output, and report printing according to corresponding standards. 

2.3.1 Test software: Chinese Windows interface, menu prompts, mouse operation; 

2.3.2 Display method: Data and curves are dynamically displayed during the testing process; 

2.3.3 Curve traversal: After the experiment is completed, the curve can be reanalyzed, and the corresponding experimental data for any point on the curve can be found with the mouse;

2.3.5 Test report: The report can be prepared and printed in the format required by the user; It has a network interface for data transmission, storage, printing, recording, and network transmission printing, and can be connected to the internal LAN or Internet network of the enterprise.

2.3.6 Limit protection: equipped with two levels of limit protection: programmable and mechanical;

2.3.7 Automatic shutdown: After the sample fractures, the moving crossbeam automatically stops; 

2.3.8 Overload protection: When the load exceeds 3-5% of the maximum value of each gear, the machine will automatically shut down;

2.3.9 The test software has a built-in standard network interface, through which test data can be transmitted to the network. The software manual and help documents provide detailed instructions and usage configuration methods for this interface. Network software can exchange and transmit data with the test software through this interface. We assist users in networking, but do not separately customize network interfaces for users, nor do we assume the responsibility of negotiating and coordinating with relevant network companies. If it involves dispatching software personnel to provide on-site service to users, corresponding fees will be charged. 

Both automatic and manual modes are used to obtain experimental results and automatically generate reports, making the data analysis process simple.
