Software features

1. Language selection: English or Russian interface freely switch operation,

2. Basic functions: calculate and list data graphics: the basic parameters of a material testing machine: (1).Yield point(2).0.2% off set.(3). Yield strength(4). Tensile strength(5). Elongation(6). Energy absorption(7). Maximum(8). Rupture values(9). Deformation amount (10). Averages. More than twenty parameters contrast to graphics.

3. Multiple curve display mode: Stress - strain, Force - displacement, Force - time, Strength –Time and other curve patterns.  

4. Control mode: fixed displacement, fixed speed, constant strain rate, fixed load, fixed load rate, fixed strain rate, etc.

5. Dynamic display: during the test, the load, elongation, displacement and experimental curves selected as testing, real-time dynamic display on the main screen.

6.Automatic identification ,storage: test conditions, test results, regression 7.Graphical Analysis: after the test is completed, you can use the mouse to view data from the test curve, any point on the test curve can be enlarged analysis, and choose Print. 8. Report Output: Graphics and arguments are opened to customers and can be modified as required. It can output different report formats, convenient and easy to learn practical.
