How to stop the tensile testing machine?

Regarding the landlord's question, the second child of the testing machine thinks that the tensile testing machine suddenly stops running for the following reasons:

During the 1. test, there may be a problem with the internal power supply of the tension machine. If the power is too small, the material will not stop pulling, so that it can't be pulled to half and can only stop there.

2. It is also possible that the internal motor will stop working immediately because it does not rotate after long-term use.

3. Check whether the screw is stuck or deformed. If so, it should be replaced immediately.

4. Check whether the worm of turbine drive is worn. If it is worn, replace it with a new one immediately.
