4. Operating Instructions
To obtain a reading:
- Insert Finger: Open the clamp of the oximeter. Insert one of your fingers (preferably the index or middle finger) into the rubber opening, ensuring your fingertip is aligned with the red light sensor.
- Activate Device: Release the clamp. The device will automatically switch on and begin measurement.
- Read Results: Remain still. After approximately eight to ten seconds, your SpO2 (blood oxygen saturation) and Pulse Rate (PRbpm) will be displayed on the OLED screen.
For accurate readings, it is recommended to use the device in a stationary condition, avoiding movement during measurement.

8. Troubleshooting
If you encounter issues with your WRINERY Pulse Oximeter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after power on | Batteries are dead or incorrectly installed. | Replace batteries or re-install them with correct polarity. |
| Inaccurate or unstable readings | Finger not inserted properly; movement during measurement; cold fingers; nail polish or artificial nails. | Re-insert finger correctly; remain still; warm hands; remove nail polish/artificial nails. |
| Device automatically turns off | No finger detected for a period (normal auto-off function); low battery. | This is normal behavior if no finger is present. If a finger is present, check/replace batteries. |
