What is a healthy trigger reading?

A healthy analog trigger ramps smoothly from 0 to 100 with steady pressure and reaches 99 to 100 at full pull. Left and right max reach should match within a few percent.

Can this test PS5 adaptive triggers?

Browsers can only read trigger travel from 0 to 1. They cannot command adaptive resistance. This page verifies travel smoothness and range, which is what matters for detecting worn triggers.

Trigger Test: check LT and RT travel online

Q: Why does my trigger jump straight to 100 percent?

Your browser or driver reports that trigger as digital only. The physical trigger may be fine. Test in Chrome or Edge over USB, which expose analog pressure on most pads.

You are in the right place. This free tool measures analog travel, max reach and symmetry for both triggers. Pull each trigger slowly in the live tester below.

Symmetry gap (max LT vs max RT): 0%

A healthy analog trigger ramps smoothly from 0 to 100. If a trigger jumps straight to 100, your browser or driver reports it as digital only.

How it works

How to test triggers in 30 seconds

01
Pull slowly
Squeeze LT from rest to full pull over about 3 seconds. A healthy bar climbs smoothly instead of jumping.
02
Check max reach
Full pull should read 99 to 100 percent. A trigger that stops at 70 or 80 has a worn sensor or blocked travel.
03
Compare sides
Repeat with RT. Both peaks should match within a few percent. A large symmetry gap points to the weaker trigger.

Reading results

Analog vs digital vs worn

Healthy analog

Badge reads analog, travel ramps 0 to 100 smoothly, max reach hits 99 to 100. Nothing to fix.

Digital only

Badge reads digital and the bar snaps to 100. This is a browser or driver limit, not a broken trigger. Retest in Chrome over USB.

Worn trigger

Analog badge but jittery travel, dead spots, or max reach stuck below 95. Clean around the trigger hinge, then retest.

FAQ

Frequently asked questions

Why does my trigger jump straight to 100 percent?

Your browser or driver reports that trigger as digital only, so intermediate pressure values never arrive. Chrome or Edge over USB exposes analog pressure on most Xbox, PlayStation and PC pads.

What max reach should a healthy trigger show?

99 to 100 percent at full pull, with left and right matching within a few percent. Persistent readings under 95 on one side suggest wear or obstruction.

Do Switch triggers test the same way?

Switch ZL and ZR report shorter analog travel than Xbox or PlayStation triggers. Confirm a smooth 0 to 100 sweep rather than expecting a long physical pull.

Can web testers check PS5 adaptive resistance?

No. The Gamepad API has no output for trigger resistance motors. Travel smoothness and full range are the reliable health signals available in a browser.
