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.

  1. Start the test.

  2. Put a 27mm-29mm diameter contact straight down onto the surface of the touchpad for at least five seconds.

  3. Remove the contact. PTLogo will automatically verify that the confidence bit was cleared in the required time and remained cleared for the contact lifetime. If no reporting errors are detected, the test will automatically pass the iteration.
