Analog Trigger (LT / RT) Calibration Test
Check analog trigger travel, pull depth percentage, deadzones, and hair-trigger trigger stops with 3-decimal float precision.
Plug in your controller & press any button, or test using keyboard emulation / auto demo.

Overview & Diagnostic Methodology
Analog triggers (LT/RT or L2/R2) rely on Hall Effect magnetic sensors or potentiometers to measure progressive squeeze depth for racing accelerators and FPS hair-triggers.
Key Diagnostic Parameters
How to Test Step-by-Step
- 1Gently pull the Left Trigger (LT / L2) and watch the gauge rise smoothly from 0% to 100%.
- 2Release the trigger and ensure it snaps all the way back to 0.000 without sticking.
- 3Repeat with Right Trigger (RT / R2).
What This Test Verifies
Frequently Asked Questions
Why does my trigger only reach 85% or 90%?
Worn silicone rubber dampening pads under the trigger hinge can physically stop the trigger before the sensor hits 1.000.
How do hair-trigger stops affect trigger testing?
Physical trigger stops limit the mechanical stroke. If your controller has trigger stops engaged, the trigger may register 100% saturation early or may require software recalibration to reach full value.
