Running a Test
Before you start running a test, be sure to complete the procedures in “Setting Up
for a Test”.
1. Ensure the extensometer arms are open.
2. Insert a specimen into the grips.
3. Close the extensometer arms.
4. Perform the test.
5. When the test is complete, open the extensometer arms.
Note The crosshead return can be done with the arm open (the Teflon slide
reduces friction between the arms and the cam). In the case of intensive
testing, it is normal to see a thin layer (white) of Teflon on the cam.
