Precisely detect wheel performance, identify physical faults, evaluate scrolling accuracy and stability. E support forward/reverse testing, real-time data monitoring, and event logging.
📖 Intro:
Monitor mouse wheel scroll interval time (ms) in real-time to evaluate response speed and stability. Shorter intervals indicate more responsive and better performing wheels.
Pro detection of wheel backscroll (Scroll Jitter) issues. When reverse scrolling na detected, red warnings appear and error counts increase, accurately identifying hardware faults.
E support both upward and downward scroll test modes, allowing independent testing of each direction for comprehensive wheel health assessment.
Real-time feedback dey show green arrow for normal upward scroll, blue arrow for normal downward scroll, and red exclamation when backscroll fault show.
E gives up to 500 lines of scroll test data and measures how many lines each wheel tick dey move, so you fit judge accuracy and consistency.
E keeps full scroll event records, including time stamp, scroll direction, and error events, so problem analysis go easier.
Wheel backscroll na when you scroll upward and the mouse suddenly jump downward, or you scroll downward and e jump upward. This one usually happen because encoder don gather dust, wear don show, or hardware don begin fail. During test, if scroll goes the opposite direction from the selected mode, the tool shows red "!" mark and adds to the reverse error count.
Do the following tests to check wheel condition:
If reverse errors dey happen often, the wheel likely get physical fault.
Average interval time helps show wheel response speed and stability:
Average interval time suppose remain fairly stable during scrolling. If e dey jump too much, that fit point to problem.
Wheel wahala commonly show for these cases:
Depending on how bad the problem be, try these repair methods:
Most physical problems go need mouse opening for cleaning or part replacement.
Think about repair or replacement when:
Dis tool helps you make better decision because the result shows the problem in clear numbers.
The tool uses JavaScript to monitor wheel events and calculate these values:
deltaY value, whether up or downAll calculations happen locally inside the browser in real time, so no server processing dey needed.
Yes, this tool works with both wired and wireless mice. Just make sure your wireless mouse connect well and battery still strong. Some wireless mice fit get slightly different wheel behavior, but the test principle stays the same. If the result looks abnormal, try these things:
