Automatic Stop with grips opened 
The new version of the instrument incorporates a feature that automatically brings the specimens to the fully open position when the test is stopped.
Fatigue and crack growth tests are very sensitive to test variables.
The new feature contributes substantially to the increase in the repeatability of the results.
