The universal testing machine can also make bending and flexural test, shear test, peel test, high and low temperature test, assurance loading test, wedge test, etc. if equipped with relative test fixtures.

4. software introduction
4.1. Defined function: according to different types of users, different material properties, different test standards, different languages, flexible setting the test program to meet the test requirements.
4.2. Input Function: Entry specimen parameters before the test, you can single input sample parameter, you can also batch input sample parameters, you can modify the sample parameters before the test, the specimen parameters can be modified after the test, fully satisfy your operating habits.
4.3. In metal tensile test, Can automatically obtain Fel,Feh,Fp,Ft,Fm,Rel,Reh,Rp,Rt,Agt,Z,A,Rm, etc,Also can carry on the artificial recognition of for Fel, Fm, etc. and print the results accordingly. Can print different content of the report and curve according to the need.
4.4. Testing standard:The program use the open database structure, integrating national,ISO,ASTM,JIS,DIN and other test method, also can customize as request;
Can configure multiple sets of force sensor and extensometer, the user can switch at any time according to need.
4.5. Data processing query functions: fully equipped data query function, print function, the export function to ensure the accuracy of the test data, reliability, real embody and reflect the nature and characteristics of the material test data.
4.6. Curve point traversal functions: Through the mouse click on the curve of force and deformation values, to obtain various parameters of each point.
4.7. Curve selection function: force-time, deformation-time, force-deformation, force-displacement four curves can be selected according the necessity to display and print; and we can switch observation at any time, any zoom (zoom in or zoom out), move it horizontally or vertically, and high-speed sampling at real-time.
4.8. Auto saving: adopting the the database management way, the test data and curve automatically saved after the test.
4.9. Automatic analysis:Finish test, the system automatically analysis, statistical test results.
4.10. Test report: According to user required format to compile reports and can print bulk data.

Standards:
Load meets or exceeds the following standards: ASTM E4, ISO75000-1, EN 10002-2,
BS1610, DIN 51221.
Strain measurement meets or exceeds the following standards: ASTM E83, ISO 9513,
