What are the protection functions of tensile testing machines?

Break protection: After selection, the test stops automatically after the sample is broken;
Load protection:
Upper limit protection: if the load value is greater than the set value, the test will be stopped;
Lower limit protection: if the load value is less than the set value, the test will be stopped;
Full protection: if the load value is greater than (full degree + full degree × set value), the test will be stopped;
Starting storage: When the load value is greater than the set value, the test data will be recorded and the curve will be drawn. If not selected, the test will be recorded and the curve will be drawn.
Pressure protection:
Percentage: During compression, bending, shear test, if the load value is less than (the load of this test × set value), the test will stop;
Start value: If the load value is greater than the set value, the pressure protection begins to take effect;
Displacement protection:
Upper limit protection: if the displacement value is greater than the set value, the test will be stopped
Lower limit protection: if the displacement value is less than the set value, the test will be stopped
cycle:
Cycle protection: If the number of cycles is equal to the set value, the test will be stopped (for dynamic tests)
Deformation protection:
Upper limit protection: if the deformation value is greater than the set value, the test will be stopped
Lower limit protection: if the deformation value is less than the set value, the test will be stopped
Extension gauge: When the deformation value is equal to the set value, the test starts to hold the load, and the extension gauge is prompted.
