Jinan public standard to help you identify the error of the universal testing machine results? -Huaqiang Electronic Network

Universal testing machine is a leading test instrument in China. It is advanced in technology, high in automatic water quality and high in test accuracy. Widely used in rubber, plastic, pipe, canvas, aluminum profiles, wire and cable, plastic film, steel wire, cord, copper, metal and non-metal materials and other related industrial materials. The control software can automatically calculate the conventional data such as elastic modulus, yield strength, tensile strength, breaking strength, sample elongation, and section shrinkage, and can automatically calculate the force, stress, displacement and other data at a certain point during the test. result. It is suitable for all kinds of testing machines such as electro-hydraulic servo universal testing machine and torsion testing machine. 1. Random error of universal testing machine: that is, repeated measurement of the same parameter under the same conditions, the obtained measured value is impossible It's exactly the same. Causes: 1 During the test, the friction of the test machine changes 2 the change of the environmental humidity, etc. 2. The error of error: the error caused by the error in the test work, negligence and so on. This kind of error is irregular and needs to be repeated by the other party to avoid. Cause: The electronic universal testing machine is operating incorrectly. The tester misreads the number and writes the wrong decimal point position. 3. Universal test machine system error: keep a certain value or a certain regular error. The systematic error is regular. This kind of law is reflected in every specific experiment. Once this law is found, it can be corrected. Causes: 1 The universal test machine is not accurate, and the measured force value is always too large or too small. 2 resistance strain gauge when measuring strain, the error of the coefficient on the instrument panel The universal testing machine control system is the system that controls the operation of the testing machine. People can control the operation of the testing machine through computer operation, and the status of the testing machine can be known through the computer display. Various test parameters can also be realized by computer and data processing analysis and test result printing. The communication between the test machine and the computer generally has a multi-function USB interface to transmit signals. It communicates through the serial port (COM port) behind the computer. This technology is mature, reliable, and easy to use. The computer software is used to collect and process the analysis. data. After entering the test interface, the computer will continuously collect various test data, draw test curves in real time, automatically print out the test results parameters and curve reports, etc. The universal test machine control system is the system that controls the operation of the test machine. Control the operation of the test machine, the status of the test machine and various test parameters can be obtained through the computer display screen, and the functions can be realized by the computer and data processing analysis and test result printing.
