Running the test
Before you run the test, complete the test setup as described in the test requirements: Mouse or other Pointing Device Testing Prerequisites.
This test requires very precise movement in a straight line. We recommend that you perform this test by using a precision rig or other precision device that is capable of straight line movement without any jitter.
Place two precision contacts 11mm apart slightly outside the top edge of the touchpad.
Drag the contact in a straight line from top to bottom across the touchpad.
Drag the contact the other direction from bottom up to top.
Repeat this pattern for a total of five iterations.
