Microcomputer control electronic universal testing machine of WDW series

 Performance features
This machine drives the cross beam to move by using an AC servo motor. The product is configured with a full -digital multi-channel closed-loop measurement and control system, which is the latest generation of measurement and control system developed by adopting a number of advanced professional technologies. The control software can automatically calculate out tensile strength, yield strength, modulus of elasticity and strength of non-proportional elongation RP0.2, and other routine data; can achieve three "closed-loop" control; as well as display real-time force -displacement, force-time, stress -strain and other forms of test curves during the test, which can be switched, observed and compared automatically. The computer control system' control of test process and data processing are in full compliance with the requirements of China's national standard.
u Automatic zeroing, automatic shift or at all shifts, automatic calibration, automatic saving, which can select single control mode or multi-step programmable mode for testing. Automatic shutdown after the fracture, automatic data storage, automatic analysis, which can aided with manual analysis, batch test, batch processing, and automatic statistics of results. Beautiful interface, fully functional, simple to extend, easy to operate, safe and reliable.
