1. Make sure the grip is open and ready to accept the specimen.
2. Use the slider controls to move the specimen up and into the upper grip.
Important: Your station setup will determine whether you have to move in the positive
or negative direction.
Switch to Force Control
Switching to force control helps ensure that you do not impart excessive force on the specimen during
installation. Once in force control, the controller will follow your positioning commands while working to
maintain the force that you specify—in this case 0 N.
1. In the Station Manager main window, click the Manual Command icon.
2. Set Control Mode to Force .
3. Set Manual Cmd to 0 N .
Clamp the Specimen in the Upper Grip
Using the limits that you set earlier and having the load frame in force control during clamping help
ensure that excessive force is not imparted on the specimen during clamping. Nevertheless, there may
be times when you have to recover from a tripped limit that occurs during the clamping process.
Instructions for that situation are provided below.
