- Finger Sensor: Where the finger is inserted for measurement.
Setup
1. Battery Installation
The Wellue Fingertip Pulse Oximeter requires two AAA batteries for operation.
- Locate the battery cover on the back of the device.
- Slide the battery cover off.
- Insert the two AAA batteries according to the polarity indicators (+/-) inside the compartment.
- Replace the battery cover by sliding it back into place until it clicks securely.
Note: Ensure batteries are inserted correctly. If the device will not be used for an extended period, remove the batteries to prevent leakage.
Operating Instructions
1. Taking a Measurement
To obtain an accurate reading:
- Ensure your finger is clean and free of nail polish or artificial nails.
- Open the clamp of the oximeter.
- Insert one finger (preferably the index, middle, or ring finger) into the rubber opening of the oximeter, ensuring the finger is placed correctly with the nail facing upwards.
- Release the clamp. The device will automatically power on and begin measurement.
- Keep your hand still during the measurement. Movement can affect accuracy.
- The SpO2 and Pulse Rate readings will appear on the display within approximately 8 seconds.

2. Understanding the Display
The OLED display shows the following information:
- %SpO2: Blood Oxygen Saturation level.
- PR bpm: Pulse Rate in beats per minute.
- Pulse Bar Graph: Indicates the strength of the pulse.
- Pulse Rate Wave: A waveform showing the pulse rhythm.
- Battery Indicator: Displays remaining battery life.

3. Spot Check Mode
After approximately 30 seconds of continuous measurement, the oximeter will display an analysis result of the pulse rhythm and SpO2. This is the "Spot Check" mode, providing a quick assessment.

4. Built-in Memory Function
The device can store up to 12 groups of SpO2 and Pulse Rate data. You can quickly view your last 12 historical data points directly on the screen with a single click of the operation button.

5. Audible and Visual Reminders
The oximeter is equipped with an alert system. If your oxygen level or pulse rate values exceed preset limits during measurement, the device will emit an audible beep, and the exceeding value will flash on the screen to draw your attention.
Maintenance
1. Cleaning the Device
To ensure hygiene and proper function:
- Clean the surface of the oximeter with a soft cloth dampened with 70% isopropyl alcohol.
- Do not immerse the device in water or any other cleaning solution.
- Allow the device to air dry completely before storage or next use.
2. Storage
Store the oximeter in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity. Use the provided carry pouch for protection when not in use.
3. Battery Replacement
When the battery indicator shows low power, replace the batteries promptly to ensure accurate readings. Refer to the "Battery Installation" section for instructions.
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 |
|---|---|---|
| Device does not turn on. | Batteries are dead or incorrectly installed. | Replace batteries or ensure they are inserted with correct polarity. |
| Inaccurate or unstable readings. | Finger not inserted properly; excessive movement; cold fingers; nail polish/artificial nails. | Reinsert finger correctly, keep still, warm hands, remove nail polish/artificial nails. |
| Display shows "Finger Out" or similar message. | Finger not detected or removed. | Ensure finger is fully inserted into the sensor. |
| Audible alarm sounds. | SpO2 or Pulse Rate values are outside preset limits. | Check readings. If values are consistently low or high, consult a medical professional. |
