Extended usage method of microcomputer screen display universal test machine

In the disk screw tensile test, the yield strength is not obvious, and it is necessary to use an extended meter to measure it.Microcomputer screen display universal test machineHow to use the extensionWhat's like?

1. Clam the sample according to the conventional experimental clamping method;

2. Clip the extensometer onto the sample. The edge of the extensometer must be close to the surface of the sample (can be tightened and fixed with rubber bands). The two edges of the extensometer must be adjusted to the position of the gauge distance (there are positioning tubes and positioning pins on the extensometer).

3. Start the tensile test and remove the extensometer after the R position appears and the sample has not broken. (Article editor: http://www.hssdtest.com/)
