Professional Mouse Tester Features

📖 Introduction:

Visual Feedback

Color changes distinguish operation types: Light blue for single-click, green for normal double-click, red for faulty double-click. The data panel highlights the corresponding button area.

Color Coding: Single-Click(Blue), Normal Double-Click(Green), Faulty Double-Click(Red)

Button Function Test

Comprehensively tests all mouse buttons including left, right, middle, and side buttons. Real-time display of press and release counts to accurately identify sticking or unresponsive buttons.

Tip: Press and release counts should match for a normal button.

Double-Click Detection

Automatically identifies double-click actions, distinguishing normal double-clicks (200-500ms) from faulty ones (<80ms). Abnormal intervals may indicate mechanical failure or micro-switch wear.

Scroll Wheel Counting Test

Tests mouse wheel up and down scrolling functions with independent counts. Useful for testing scroll encoder performance and scrolling sensitivity.

Tip: Watch for bounce-back or stuttering when testing the scroll wheel. Dedicated Scroll Wheel Test

Real-time Event Log

Logs timestamps and details of all mouse actions, including button state changes, scroll wheel actions, and double-click events for easy problem diagnosis and analysis.

Log shows up to 20 latest records.

Test Area Status

Test area border color reflects real-time status: Blue (Active), Light Blue (Testing), Green (Double-click detected), Red (Fault).

Frequently Asked Questions (FAQ)

How do I test mouse button functions?

Press any mouse button. The corresponding 'Pressed' counter on the right will increase. When you release the button, the 'Released' counter also increases. If the counters don't change, the button might be faulty. A normal button should respond to both press and release actions.

How do I test mouse side buttons?

Press the mouse side buttons (usually labeled B4 and B5). The corresponding 'Pressed' and 'Released' counters for the side buttons should increase. If they don't, the side buttons might be faulty. Side buttons are usually located on the left side of the mouse for browser forward/back or custom functions.

What do 'Pressed' and 'Released' counts mean?

The 'Pressed' count tracks how many times you've pressed the button down. The 'Released' count tracks how many times you've let go of the button. For normal mouse operation, these two numbers should match when you release the button. A mismatch might indicate the button is sticking or not releasing properly. A large difference suggests a mechanical issue.

Why is the counter showing a number higher than my actual clicks?

This most likely indicates abnormal button contact, possibly caused by:

  • Micro-switch aging or oxidation causing poor contact
  • Dust accumulation inside the button
  • Physical damage causing frequent contact make/break
Recommended dedicated test: Dedicated Double-Click & Multi-Click Test

Why does the scroll wheel test separate 'Up' and 'Down' counts?

Separate counts for scroll up and down help diagnose specific issues with the scroll wheel encoder. For example, if only 'Up' counts increase while 'Down' doesn't respond, it may indicate poor contact or damage in one direction of the encoder.

How do I know if my mouse needs replacing?

Consider replacing your mouse if you notice the following:

  • 1) Buttons don't respond when pressed;
  • 2) Random double-clicks or multi-clicks occur, and a dedicated double-click test confirms it's a mechanical fault;
  • 3) Scroll wheel is not smooth or scrolls backwards, and a dedicated scroll wheel test confirms it's a mechanical fault;
  • 4) Side buttons don't work.

This tool can help you systematically diagnose these issues.
