2.according to the standard.

The electronic universal testing machine meets the requirements and standards of GB/T 1040-2006, GB/T 1041-1992, GB/T 1042-1992, GB/T 10802-2006, GB/T 10807-2006, GB/ t10808-2006.

3. Function introduction.

A) this electronic universal testing machine adopts the built-in controller, which guarantees that the test machine can achieve constant speed displacement control.

B) servo motor is adopted, with stable performance, over-current, overpressure, overspeed, overload and other protective devices.

C) the electric control circuit is in accordance with the international standard, which conforms to the national testing machine's electrical standard and strong anti-interference ability, which guarantees 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; In the real sense, the physical adjustment, gain adjustment and test force measurement of automatic shift, zero, calibration and storage, without any analog adjustment, the control circuit is highly integrated.

E) conditional storage: test control data and sample conditions can be made into modules to facilitate the batch test;

F) automatic transmission: the speed of moving the beam in the test process can be changed automatically according to the preset procedure, or it can be changed manually;

G) automatic calibration: the system can automatically realize the calibration of indicator accuracy;

H) automatic saving: the test is finished, the test data and curve are saved automatically;

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

J) batch test: the sample of the same parameters can be completed after one setting;

K) test software for electronic universal testing machine: Chinese WINDOWS interface, menu prompt, mouse operation;

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

M) curve traversal: after the completion of the experiment, the curve can be reanalyzed, and the corresponding experimental data can be found with the mouse.

N) curve selection: the stress - strain, force - displacement, force - time, displacement - time and other curves can be selected to display and print.

O) test report: the report can be prepared according to user's requirements and printed; With network interface, data transmission, storage, printing records and network transmission printing can be connected to Intranet or Internet network.

P) limit protection: it has two levels: program control and mechanical protection;

Q) automatic stop: after the sample is broken, the moving beam will stop automatically;

R) overload protection: when the load exceeds 3-5% of the maximum value of each gear, automatic shutdown, automatic and manual mode to obtain test results, automatically form the report, making the data analysis process simple.
