What the test detects
The tester records each pointer event and compares the time since the previous event. If two inputs arrive inside the selected threshold, the pair is flagged as a possible double-click. This helps reveal switches that produce two electrical signals from one normal press.
How to test fairly
- Click slowly and deliberately rather than intentionally double-clicking.
- Test the left, right, and middle buttons separately when possible.
- Try another USB port or a wired connection before blaming the switch.
- Compare the result with the operating system's double-click setting.
A flagged pair is not always a fault
Fast intentional clicks can fall inside the threshold. Browser scheduling and touchpads can also produce unusual patterns. Repeated flags during slow single clicks are more meaningful than one isolated result. See why a mouse starts double-clicking for a complete diagnostic sequence.
