Set Limits
You can use MPX limit detectors to protect you, your specimen, and the equipment. When a limit is tripped,
an action is carried out (for example, Controlled-Stop Interlock). You can set both the limit values and the
actions.
In this section, you will set nested displacement and force limits. MTS highly recommends mastering the
concepts presented in
Understanding Nested Limits (p. 80) prior to performing the steps in this topic.
The forces and displacements of interest for this example test are:
