Test Procedure
- Pre-test inspection: Confirm the sample powers on normally, display is fully lit with no missing segments, and all buttons are functional.
- Endurance cycling — Power button: Actuate the power button 5,000 times using the sensor test fixture.
- Endurance cycling — Unit-switch button: Actuate the unit-switch button 5,000 times.
- Endurance cycling — Inflation trigger: Actuate the inflation trigger 5,000 times.
- Endurance cycling — Deflation button: Actuate the deflation button 5,000 times.
- Post-cycle functional check: Verify display illumination (no dimming, no missing segments), power button operation, and unit-switch button operation.
- Accuracy verification at 40 psi: Apply 40 psi reference pressure; record gauge reference value and T500 displayed value; delta must be within ±1 psi.
- Accuracy verification at 90 psi: Apply 90 psi reference pressure; record gauge reference value and T500 displayed value; delta must be within ±1 psi.
- Accuracy verification at 120 psi: Apply 120 psi reference pressure; record gauge reference value and T500 displayed value; delta must be within ±1 psi.
- Acceptance criteria:
- Display lights normally — no dimming, no missing digit segments.
- Power button and unit-switch button function correctly after 5,000 cycles.
- All pressure readings differ from the reference gauge by no more than ±1 psi.

Frequently Asked Questions
How many cycles did the ETENWOLF T500 tire pressure gauge endure in the life cycle test?
The T500 was subjected to 5,000 actuation cycles across each of its four buttons — the power button, unit-switch button, inflation trigger, and deflation button — completing a total of 20,000 individual actuations across all controls.
Did the T500 maintain pressure accuracy after 5,000 life cycles?
Yes. Post-cycle accuracy testing at three pressure points showed the T500 remained well within the ±1 psi tolerance: it read 40.0 psi against a 39.8 psi reference, 89.9 psi against 89.7 psi, and 119.9 psi against 119.7 psi — a consistent delta of only 0.2 psi across all points.
What is the acceptance criterion for the T500 life cycle test?
The T500 must satisfy two criteria after 5,000 cycles: (1) the display must illuminate fully with no dimming or missing digit segments, and the power and unit-switch buttons must operate correctly; (2) pressure readings at 40 psi, 90 psi, and 120 psi must each differ from the reference gauge by no more than ±1 psi.
What standard governs the ETENWOLF T500 life cycle test?
The test is conducted to ETENWOLF’s internal reliability standard, which specifies 5,000-cycle mechanical endurance for all operator controls and a ±1 psi pressure accuracy tolerance verified at low (40 psi), mid (90 psi), and high (120 psi) pressure reference points.
