Detailed explanation of the operation characteristics of hydraulic universal testing machine

Hydraulic universal testing machineThe digital display device is a new generation of universal machine control system independently developed by Jinan Hengsi Shanda Instrument Co., Ltd., which can automatically obtain yield strength, tensile strength, automatically store data, and has query and networking functions. With a set of microcomputer and rotary encoder, it can be upgraded to a screen-explicit universal machine; if a set of servo control system is added, it can be upgraded to a servo universal material testing machine. When our company leaves the factory, there are reserved interfaces from the host to the control system, which can be upgraded at any time according to user needs to meet the user's usage requirements in different occasions.

4. Storage: The data in this instrument can still be retained after power off. After power is restored, the original data can be retrieved and printed by printing. If you use communication software, you can also communicate with the microcomputer,Hydraulic universal testing machineComputer data archives and references may be centrally stored by the management center through the networking to facilitate quality supervision and microcomputer management. The storage volume in this instrument is 446 test units, that is, the numbers are 01~446|. When you enter 447 numbers, the numbers are cleared. The data numbered after the data is stored is cleared

1, "FFF" is displayed, indicating that it is unqualified

The current pressure value of the force measuring instrument or force measuring ring can be manually input, close the oil return valve, open the oil supply valve, and allow the piston to rise by 4-5mm. Press "Clear" and continue to open and send the oil valve. When the current pressure value reaches the standard value of the force measuring instrument or force ring, press the "Confirm" key. The 0.00 position in the upper box will display the error percentage of the current verification point (such as 50KN) (such as 0.24, indicating that the error of the 50.0 point is 0.24%). At this time, the standard value is displayed as 100KN point. Continue to open and send the oil valve. When the current pressure value reaches the standard value of the force measuring ring, press the "Confirm" key. The 0.00 position in the upper box will display the error percentage of the next verification point (such as 100KN), and so on until all verification points are checked. The box below the instrument shows End-. Indicates that the calibration has ended, press the "Exit" key. Return to the test status.

If "FFF" does not appear at 0.00 of the box above the calibration pointing process, it means that the press is qualified for verification, otherwise the following steps will be followed to recalibrate.
