8.2.5.0 Transition Parameters
Transition parameters include:
• Inelastic Strain Transition Limit
• Test Time Limit
• Transition Maximum Stress Percent Change
• Transition Monitoring Minutes
• Transition Stress-A Ratio Percent
After an amount of time passes equal to the test time limit minus the transition monitoring minutes, monitoring
begins for the following conditions:
• Inelastic strain does not exceed the Inelastic strain transition limit.
• Maximum stress does not change more than the Max Stress percent change amount.
• Stress-A Ratio does not change by more than the Stress-A ratio percent change amount.
Monitoring occurs for the amount of time specified as the transition monitoring minutes.
If the test passes this criteria, the application shows a message. Click OK to end the test. The application
transitions to load control.
8.2.6.0 Load Test Parameters
Load test parameters include:
• Gage length load control
• Load end level 1
• Load end level 2
• Load frequency
Enter values as necessary and click OK.
