from the grips.
1. If needed, provide adequate support for the specimen, and turn the upper
grip control to the release position.

provide adequate clearance for removal of the lower part of the specimen.
Reposition the crosshead or actuator, as needed.

grip control to the release position.
5. Remove the specimen.
