- Release the clamp.
- Press the power button on the front panel to turn on the device.
- Keep your hand still during the measurement. Readings for SpO2 and PR will appear on the display within a few seconds.
4.2 App Functionality
When connected via Bluetooth, the app provides enhanced features:
- Real-time Data: View SpO2, PR, and pulse waveform directly on your smartphone.
- Continuous Recording: The app can record data for up to 10 hours continuously. Note: Recording only occurs when the app is actively running on your device.
- Graphic Reports: Access historical data and trends in a graphical format.
- Data Sharing: Generate and share reports (e.g., PDF format) of your blood oxygen and pulse rate data.

6. Troubleshooting
If you encounter issues with your Wellue Fingertip Pulse Oximeter, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after pressing power button | Batteries are dead or incorrectly installed. | Replace batteries or ensure correct polarity. |
| Unstable or inaccurate readings | Finger not inserted correctly, finger too cold, patient movement, nail polish/artificial nails. | Reinsert finger properly, warm finger, remain still, remove nail polish/artificial nails. |
| No SpO2 or PR reading | Finger not inserted, probe not connected (internal issue). | Ensure finger is fully inserted. If problem persists, contact support. |
| Bluetooth connection issues | Bluetooth off on phone, app not open, device not discoverable. | Ensure phone Bluetooth is on, open app, restart oximeter. |
