Setup
- Battery Installation: Open the battery compartment on the back of the gauge. Insert the 2 AAA batteries provided, ensuring correct polarity. Close the compartment securely.
- Connect Hose: Attach the heavy-duty rubber hose to the main gauge unit by screwing it into the designated port. Ensure it is tightened securely to prevent air leaks.
- Prepare for Air Compressor (for inflation/deflation): If you intend to use the 3-in-1 inflation/deflation features, connect the 1/4" NPT quick-connect coupler to your air compressor's hose. Use the included thread seal tape on the threads for a secure, airtight connection.
Operating Instructions
The AUTDER Digital Tire Pressure Gauge is designed for ease of use across various vehicle types, including cars, trucks, motorcycles, and bicycles.
1. Power On/Off and Unit Selection:
- Press the "ON/OFF" button to turn on the gauge. The backlit LCD screen will illuminate.
- To cycle through measurement units (PSI, KPA, BAR, KG/CM²), press the "UNIT/LED" button repeatedly until your desired unit is displayed.
- The gauge features an automatic shut-off function to conserve battery life after a period of inactivity.
Figure 3: The large backlit LCD display provides clear real-time tire pressure values and battery level indication.
2. Measuring Tire Pressure:
- Ensure the gauge is powered on and the desired unit is selected.
- Firmly press the air chuck onto the tire's valve stem. You may hear a slight hiss of air; this is normal.
- The digital display will show the current tire pressure reading. The gauge provides highly accurate readings with an accuracy of ±1% and a resolution of 0.1.
- Remove the air chuck from the valve stem. The reading will remain on the screen for approximately 30 seconds before automatically clearing or shutting off.
Figure 4: The gauge provides accurate measurements in 0.1 increments, with readings consistent for 30 seconds.
3. Inflating Tires:
- Connect the 1/4" NPT quick-connect coupler to your air compressor.
- Attach the air chuck to the tire's valve stem.
- Press the "Push-to-Inflate" thumb trigger to begin inflating the tire. Monitor the digital display for real-time pressure readings.
- Release the thumb trigger once the desired tire pressure is reached.
4. Deflating Tires:
- Attach the air chuck to the tire's valve stem.
- Press the built-in air bleeder valve (located near the quick-connect fitting) to release air from the tire. Monitor the digital display as pressure decreases.
- Release the bleeder valve once the desired tire pressure is reached.
Figure 5: The gauge offers three primary functions: connecting to an air source for inflation, checking current tire pressure, and deflating tires.
5. Versatile Use:
The gauge is compatible with all Schrader valve stems and most air compressors, making it suitable for a wide range of applications.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gauge does not power on. | Dead or incorrectly installed batteries. | Check battery polarity or replace batteries. |
| Inaccurate pressure readings. | Loose connection to valve stem; low battery; gauge malfunction. | Ensure a tight seal on the valve stem. Replace batteries. If problem persists, contact customer support. |
| Air leaks during inflation/deflation. | Improper connection; damaged hose/coupler; worn O-rings. | Ensure all connections are tight. Inspect hose and coupler for damage. Replace O-rings if worn. |
| LCD display is dim or flickering. | Low battery. | Replace batteries. |
