Using the controls on the load frame, release the upper grip.
9. If necessary, repeat the upper grip clamping process.
If Necessary, Recover from a Tripped Displacement Limit
There are a number of possible causes for a tripped displacement limit. For example:
• The actuator may have retracted below the lower displacement limit during specimen installation.
• The actuator may have retracted when the specimen broke at the conclusion of the test.
• Your test limits may have been insufficient for the test.
Rather than cover all possibilities, this section addresses the first case only. Adapt this procedure as
necessary to recover from other situations.
1. Check current displacement limits.
a) In the Station Manager application main window, select Display > Station Setup > Displacement
> Channel Input Signals.
b) Select the Limits tab.
c) Check the current upper and lower limit settings to identify the acceptable displacement range for
the actuator. Adjust the limits if necessary.
