Adopt the most advanced and reliable floor standing structure of main body in the world, imported all- digital AC servo speed governing system and motor, and imported load transducer, as well as full-digital designed measurement and control system, so as to achieve high precision, wide range of measurement and three "closed-loop" control.
u The measurement and control system uses high-precision converter, imported high-quality electronic devices, and adopts full-digital design, which is of "plug and play", in line with PCI2.1 specifications, and can automatically allocate the resources. Integrated dual-channel precision amplifier, with the function of "auto zero detection". Built-in large-scale CPLD programmable logic chip, which can carry out high-speed computing, and real-time processing. Full CNC adjustment and calibration, providing SingleAD software interface.
Modular design is adopted for the software. Configured with displacement, force, deformation (or stress, strain), and metal stretching and other control methods, which can also use the program editor in the software to self-compile some multistep control programs. The test data are automatically analyzed and processed according to the corresponding standards, meanwhile the tensile strength, yield strength, modulus of elasticity and stipulated non-proportional extension strength RP0.2, etc. can be calculated out. The "batch processing" program in the software package can conduct the statistics and comparison of results and curves for a batch of specimens. The test data is managed by databases, providing a several user-defined items, so as to meet some specific requirements. Flexible and diverse forms of report editing modes (including Word, Excel, and advanced customization), allowing users to print a satisfactory report.
