WDW series is a new kind of electronic universal testing machine produced by Chenda Company, which adopts the most advanced and reliable load frame structure of ball screw electric mechanical universal testing machine of the world. The driving system adopts AC servo timing system and motor. The PC controlling system is able to realize the close-loop control of the parameters such as loading force, specimen deformation, and crosshead stroke ect. The system realize the screen display, online diagram drawing, testing curve changing, fold curve collation and auto analysis of test results, creation of test report. Especially, the application of the control mode can be manual control or computer programming control which makes the cyclic tests become available.

Features:

1> Complete computer controlled: the whole measuring and controlling system adopts specific PC control card used for testing machines, realizing the data zero and plus adjustment, which has very high reliability.
2> Supporting multi-transducers.
3> Realizing the database management of the test data which are stored according to the standard format; facilitating other software to analyze and transfer.
4> Perfect programming by auto program control, every control mode can smoothly shift to another one. Fulfilling the test requirement of all kinds of materials with every test standard home and abroad.
5> Control software has the the auto-adjusting function of test hardness, which assures that the system works with every kind of specimen hardness.
6> Perfect graphic function realizing the arbitrarily magnifying, decreasing, equaling, adding, indicative display and print of all kinds of test curves, the test point searching as well as the simultaneous display and print of several kinds of test curves. Data processing supposes self-disposing and input disposing of graphic human computer interaction, which facilitates the check and contrast of the test result.
7> The user can self-define the output of the test report, which makes the report format have high flexibility.
8> Modularization design facilitated the software upgrading, function spreading as well as the second development.
