8. Determine if it is necessary to make any adjustments to the frame configuration to attain the
required test opening that was determined in step 7 . Raise or lower the crosshead as necessary -
see the appropriate procedure for your frame under “Change height of test opening - J1-style or
J3-style crosshead” on page 33 .

9. Install the desired specimen fixtures into the test space using adapters and alignment couplings as
necessary.
10. Balance the load, if necessary.
11. Install the specimen into the fixtures as specified by your test method.
12. Install extensometry, strain gauges, etc. (if applicable).
13. Reset the zero extension point, if necessary.
14. Start the test.
15. As the test is running, the controlling software dynamically displays the data that is being collected or
calculated for graphing and results. Also, the user may be prompted to perform some operation,
such as remove an extensometer. When the operation has been performed, click the appropriate
button to continue the test.
16. When the test is complete, the system will automatically stop the test as determined by the test
procedure.
17. Remove the specimen and prepare the system for another test (as applicable).
For frames with a J4-style crosshead, the crosshead is fixed and can not be adjusted.
When adjusting the crosshead, be sure the crosshead is secured in place once it is
positioned as desired:
• When the frame is equipped with a J1-style crosshead, be sure all Superbolt tensioners are
tightened to the required torque (see
“Adjust the position of a J1-style crosshead” ).
• When the frame is equipped with a J3-style crosshead, be sure that the crosshead support collars
are positioned on the columns so they are in contact with the bottom of the crosshead and they
are tightened to the required torque (see
“Adjust the position of a J3-style crosshead” .
The test can be stopped at any time by using either the
STOP TEST
button on the user control panel or
the
END TEST
button in the controlling software. This does not shut down the HPS unless the end test
action in the software is set up to perform that task.
If it is necessary at any time to shut down the HPS, press the
DISABLE FRAME
button in the controlling
software.
If the frame will sit idle between tests, press the
DISABLE FRAME
button in the controlling software to
shut down the HPS. For added precaution, engage the
Emergency Stop
button to ensure that the
HPS can not be inadvertently started. Release the
Emergency Stop
button when ready to run the
next test. Once the HPS is running, immediately check the position of the piston within the hydraulic
cylinder; the piston should be positioned so that it is neither fully retracted nor fully extended. Use the
jog controls to move the piston if necessary - typically a separation of 6 mm (0.25 in) is sufficient.
