4.2 HUAWEI Health App Installation
- Download the HUAWEI Health app from your device's app store (App Store for iOS, HUAWEI AppGallery or Google Play Store for Android).
- Open the app and follow the on-screen instructions to create a HUAWEI ID or log in with an existing one.
- Complete your personal profile information, including gender, height, and date of birth, as this data is crucial for accurate body composition analysis.
4.3 Initial Pairing (Wi-Fi & Bluetooth)
- Ensure Bluetooth is enabled on your smartphone.
- Open the HUAWEI Health app, navigate to the 'Devices' section, and tap '+' to add a new device.
- Select 'Smart Scale' and choose 'HUAWEI Scale 3 Pro' from the list of available devices.
- Step onto the scale briefly to activate it. The scale's display will light up.
- Follow the app's instructions to complete the Bluetooth pairing process.
- After successful Bluetooth pairing, the app will prompt you to connect the scale to your home Wi-Fi network. Enter your Wi-Fi credentials. Wi-Fi connectivity allows for automatic data synchronization without needing your phone nearby during measurements.
5. Operating Instructions
5.1 Taking a Measurement
For a complete body composition analysis, both feet and hands must make contact with the electrodes.
- Place the scale on a hard, flat surface.
- Ensure your feet are clean and dry. Step onto the scale barefoot, positioning your feet on the designated electrode areas.
- Pick up the handle electrode. Hold the handle firmly with both hands, ensuring your palms make full contact with the metal electrodes on the handle. Keep your arms straight and slightly away from your body.
- Stand still until the measurement is complete. The scale's display will show your weight, and then the data will be transmitted to the HUAWEI Health app.

5.2 Understanding Your Data
After each measurement, open the HUAWEI Health app to view your detailed body composition report. The app provides insights into 22 indicators, including:
- Weight
- Body Fat Percentage
- Muscle Mass
- Body Mass Index (BMI)
- Basal Metabolic Rate (BMR)
- Body Water Percentage
- Bone Mineral Content
- Visceral Fat Level
- Protein
- Skeletal Muscle Mass
- And more.
The HUAWEI Health app uses the HUAWEI TruFit™ 2.0 algorithm to interpret your data and provide personalized health assessments and recommendations.
5.3 Multi-User Management
The HUAWEI Scale 3 Pro supports multiple users. Each user should create their own profile in the HUAWEI Health app. The scale can intelligently identify different users based on their weight and body composition data. If the scale cannot identify a user, you can manually assign the measurement to the correct profile within the app.
6. Maintenance
6.1 Cleaning
- Wipe the scale surface with a soft, damp cloth.
- Do not use harsh chemicals, abrasive cleaners, or corrosive liquids.
- Ensure the scale is completely dry before storage or next use.
6.2 Storage
- Store the scale in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid placing heavy objects on the scale when not in use.
- If the scale will not be used for an extended period, remove the batteries to prevent leakage.
7. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Scale does not turn on. | Batteries are low or incorrectly installed. | Check battery polarity or replace with new AAA batteries. |
| No data synchronization to app. | Bluetooth/Wi-Fi connection issue, app not open, or scale not paired. | Ensure Bluetooth is on, app is open, and scale is paired. Check Wi-Fi connection in app settings. Re-pair if necessary. |
| Inaccurate readings. | Scale on uneven surface, feet/hands not making full contact, or incorrect profile data. | Place scale on a hard, flat surface. Ensure bare feet and palms fully contact electrodes. Verify personal data in HUAWEI Health app. |
| Scale cannot identify user. | New user, or significant weight change. | Manually assign the measurement to the correct profile in the HUAWEI Health app. Ensure all users have distinct profiles. |
