4.2 Initial Calibration
The device features automatic calibration upon power-on. Ensure the gauge is not connected to a tire during startup for accurate zero-pressure calibration.
- Press the power button to turn on the device.
- The display will show "Calibrating" or similar indication.
- Wait until the display shows "Ready to Use" or "0.0 PSI" before proceeding.
- Do not use the gauge until the calibration process is complete.

5. Operating Instructions
5.1 Checking Tire Pressure
- Ensure the gauge is powered on and calibrated (refer to Section 4.2).
- Remove the valve cap from the tire.
- Firmly press the nozzle of the tire pressure gauge onto the tire valve stem. A brief hiss of air is normal.
- Hold the gauge in place until the digital display shows a stable reading.
- Read the tire pressure from the display.
- Remove the gauge and replace the valve cap.

6. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the tire pressure gauge in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries when the display becomes dim or the device fails to power on. Always use new 3A alkaline batteries.
- Avoid Dropping: Protect the device from impacts to maintain its accuracy and functionality.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Replace batteries with new 3A alkaline batteries, ensuring correct polarity. |
| Inaccurate readings. | Improper calibration; gauge not firmly seated on valve; extreme temperature changes. | Ensure proper calibration at startup. Press the nozzle firmly onto the valve. Allow the device to acclimate to extreme temperatures before use. |
| Air leaks when checking pressure. | Gauge not properly sealed on valve stem. | Ensure a tight seal by pressing the nozzle firmly and squarely onto the valve stem. |
| Display is dim or flickering. | Low battery power. | Replace batteries. |
8. User Tips
- For optimal accuracy, check tire pressure when tires are cold (before driving).
- The T300 is designed for Schrader valves. If you intend to use it with Presta valves (common on some bicycles), a separate Presta to Schrader valve adapter will be required as it is not included with this product.
- Always ensure the gauge is properly calibrated before each use by powering it on and waiting for the "Ready to Use" indication.
9. Frequently Asked Questions (FAQ)
