III. Function introduction

A) The electronic universal testing machine adopts built-in controller to ensure that the testing machine can achieve constant velocity displacement control.

B) Adopt servo motor, stable performance, with over-current, over-voltage, overspeed, overload protection devices.

C) The electrical control circuit refers to the international standard and conforms to the national electrical standard of testing machine. The anti-interference ability is strong, which ensures the stability of the controller and the accuracy of the experimental data.

D) Automatic shift: automatically switch to the appropriate range according to the load size to ensure the accuracy of the measurement data; Realized the real sense of physical zero adjustment, gain adjustment and test force measurement of automatic shift, zero adjustment, calibration and storage, without any analog adjustment link, the control circuit is highly integrated

E) Condition saving: test control data and sample conditions can be made into modules to facilitate the conduct of batch tests;

F) Automatic speed change: the speed of moving beam in the test process can be changed automatically or manually according to the preset program;

G) Automatic calibration: the system can automatically calibrate the accuracy of the indicated value;

H) Automatic saving: at the end of the test, the test data and curves are automatically saved;

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

J) Batch test: for the sample with the same parameters, it can be completed successively after one setting;

K) Electronic universal testing machine test software: Chinese Windows interface, menu prompts, mouse operation;

L) Display mode: data and curves are displayed dynamically with the test process;

M) Curve traversal: after the test is completed, the curve can be reanalyzed and the test data corresponding to any point of the curve can be found with the mouse;

N) Curve selection: stress-strain, force-displacement, force-time, displacements and other curves can be selected according to need for display and printing;

O) Test report: report can be prepared and printed according to the format required by users; With network interface, can carry out data transmission, storage, printing record and network transmission and printing, can be connected with the internal LAN or Internet network.

P) Limit protection: with program control and mechanical two level limit protection;

Q) Automatic stop: after the sample is broken, the moving beam automatically stops;

R) Overload protection: when the load exceeds 3-5% of the maximum value of each file, it will stop automatically. The test results will be obtained in two modes, automatic and manual, and the report form will be formed automatically, making the data analysis process simple.
