Fixture preparation: tensile fixture, compression fixture, three-point bending fixture, four-point bending fixture, extensometer (small deformation) [Instrument features]: 1. It has protection functions such as overload, overcurrent, overvoltage, displacement upper and lower limits and emergency stop; 2. The built-in controller ensures that the testing machine can realize the closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize the tests of constant velocity test force, constant velocity displacement, constant velocity strain, constant velocity load cycle, constant velocity deformation cycle, etc., and can smoothly switch between various control modes. 3. At the end of the test, it can be manually or automatically returned to the initial position of the test at high speed; 4. It has a network interface, which can transmit, store, print records and network transmission and printing, and can be connected to the internal LAN or Internet network of the enterprise.
