Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

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.

A precision contact is necessary for this test. For the test to pass, the contact must be able to rest on the device with no jitter. We strongly recommend that a robot or precision rig be used to execute this test.

  1. Carefully lower one contact straight down anywhere on the touchpad.

  2. Wait ten seconds (use the timer in the upper-right corner of the Logo tool).

  3. Carefully raise the contact.

    If no jitter is detected, the tool will pass the iteration and move on to the next iteration. Otherwise it will fail the test and give an error.

  4. Repeat for five iterations.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting Device.Input Testing.

Error Description/Workaround

[12] interaction too short: #####

The contact was down for less than the required ten seconds. The number given is the duration of the contact, measured in tenths of milliseconds.

Make sure you leave the contact down for at least ten seconds.

[11] contact displacement too large: ###

Contact moved or jitter farther than the allowed tolerance. The number given is the himetric distance moved, measured in hundredths of millimeters.

Make sure the contact is completely stationary on the device.
