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: Windows Touch Testing Prerequisites.
This test can help to ensure that touch systems can effectively tolerate common environmental conditions.
This test presents two scenarios: the only distinction between the two scenarios is the power source. For the Battery portion of the test, you should remove the external power source from a mobile system.
In each case, the test validates that a contact that is held at the minimum required distance from the screen does not register any touch contacts. For precise values, see Windows Hardware Certification Requirements: Devices.
Troubleshooting
For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.
For troubleshooting information, see Troubleshooting Device.Input Testing and the Hardware Component Guidelines for Windows Digitizer Class Input Devices.
