Adjust the Grip Clamp Rate
The clamp rate determines how fast the grip can clamp a specimen. Experiment with a dummy specimen to
find the best setting.
1. Ensure that both the upper grip control and lower grip control are in the unclamp position.
2. Turn on electrical power at the test controller.
3. Turn on low or high hydraulic pressure.
4. If needed, move the crosshead or actuator so that the dummy specimen can be easily installed in the
lower grip.

This step ensures uniform tightness.
