3. Operating Instructions
3.1 Power On/Off and Unit Selection
The single button on the gauge controls power, unit selection, and zero reset.
- Power On: Press the button once to turn on the gauge. The display will illuminate.
- Change Units: While the gauge is on, press the button repeatedly to cycle through the available units: PSI, BAR, and KPA.
- Zero Reset: After taking a reading, press the button again to reset the display to zero for the next measurement.
- Power Off: The gauge will automatically power off after a period of inactivity to conserve battery life. You can also press and hold the button to manually power it off.
3.2 Measuring Tire Pressure
- Ensure the tire is cool before measuring for the most accurate reading.
- Remove the valve cap from the tire.
- Press the gauge's chuck firmly onto the tire valve stem. The 360° rotating nozzle allows for easy connection from any angle.
- Hold the chuck in place until the digital display shows a stable pressure reading. The reading will lock on the display.
- Remove the gauge from the valve stem.
- Compare the reading to your vehicle's recommended tire pressure (usually found on a sticker inside the driver's side door jamb or in the owner's manual).
- Press the gauge button to reset the display to zero for the next measurement.
- Replace the valve cap on the tire.

3.3 Using the Air Bleeder Button
If your tire pressure is too high, you can use the built-in air bleeder to release air:
- With the gauge still attached to the tire valve and displaying the pressure, locate the small bleed button on the side of the brass connector.
- Press and hold the bleed button to release air from the tire. The digital display will show the pressure decreasing in real-time.
- Release the button when the desired pressure is reached.

4. Maintenance
4.1 Cleaning
Wipe the gauge with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
4.2 Battery Replacement
When the display becomes dim or the gauge does not power on, replace the AA batteries as described in Section 2.2.
4.3 Storage
Store the gauge in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
5. Troubleshooting
5.1 Gauge Does Not Power On
- Check if the batteries are installed correctly with the correct polarity.
- Replace the batteries with new AA batteries.
5.2 Inaccurate Readings
- Ensure the gauge chuck is firmly and squarely seated on the tire valve stem to prevent air leakage during measurement.
- Verify that the tire is cool before taking a reading.
- If readings remain inconsistent, the gauge may require recalibration or service.
