About Setting Up a Test to Acquire Fatigue Data
To acquire fatigue data during your test, you should define a Group process that
includes the Fatigue process and your command process.
You should sequence your test so that:
• In the group process, the Fatigue process starts when the command process
starts.
• When the command process ends, the Fatigue process is terminated.
• When the Fatigue process ends, the Group process ends.
In this setup, each execution of the Group process yields one point of data
(which is not enough to create a fatigue plot). To acquire enough data points for
your plot, you can set the number of times the Group process runs equal to the
number of passes you desire (typically greater than one hundred).

I TEM D ESCRIPTION
Name Specifies the process name displayed on the Procedure or Group process
window.
Process Enabled Enables the process. (Clear this box to disable the process.)
Execute Process Specifies the number of times the process will be run.
Counter Type Enables a process counter.
Options are None, Transient, or Fixed. Transient counters are displayed only
when the process is active. Fixed counters are displayed throughout the test.
Counter Label Names the counter.
When you run the test, this name appears under Sequence Counters on the
MPT control panel.
Note If this box is blank, the process name is used as the counter label.
