5. At the contact point, the contact point between the edge of the test object and the tape should be aligned with the middle of the tape.
6. The tester should be tested in the most unfavorable position.
7. Sharp edge tester, force is 1.35 pounds (6N).
8. The force applied to the tape position should be light, and the edge test pressure is 1.35 pounds.
9. Sharp edge tester, start the switch shaft to rotate one circle.
10. Be careful not to cut the tape to expand its size, use a ruler to measure the length of its cut.
