It integrates measurement, control, and transmission functions, and has highly advanced signal acquisition, signal amplification, data transmission, and servo valve drive units. Integrating and adding an external manual control unit provides a new solution for the measurement, control and operation of testing machines. USB data transmission fully supports notebook computers, tablet computers, and desktop computers; it is an important part of leading the development of testing machine technology

(2) Universal testing machine measurement and control software
The measurement and control software of the universal testing machine adopts DSP technology and neuron adaptive control algorithm to realize multiple closed-loop control modes such as equal-rate test force, equal-rate cylinder displacement, equal-rate strain, etc. The control methods can be combined in any way and switched smoothly. It has a network interface and can Realize data networking and remote control functions.

(3) Equipment operation monitoring system
The equipment operation monitoring system is a subversive improvement made by our company on the original high-current circuit. It adds phase sequence, phase loss self-test indication functions, electrical overcurrent, overload and other protection functions to make the equipment operation safe and reliable.

(4) External handheld control box
It can control the rise and fall of the movable beam and the oil cylinder, and the clamping and loosening of the jaws. It also has an emergency stop function for the equipment, making the specimen clamping more convenient and the operation simpler..

(5) Pressure monitoring instrument
