5. Operating Instructions
5.1. Taking a Measurement
- Place the scale on a hard, flat surface.
- Ensure your feet are clean and dry. Step onto the scale barefoot.
- Pull out the retractable handle and hold it firmly with both hands. Ensure your hands are in contact with the electrodes on the handle.
- Stand still until the measurement is complete. The scale will display your weight, body fat, and BMI directly on its screen.
- The voice announcement function will confirm the completion of the measurement and may provide posture guidance.

5.2. Understanding 8-Electrode and Dual-Frequency BIA
The Healthkeep scale utilizes 8 electrodes (4 on the platform, 4 on the retractable handle) and dual-frequency BIA technology for enhanced accuracy. This method measures bioelectrical impedance across different body segments (arms, legs, trunk) and at both low and high frequencies.
- Low Frequency (25kHz): Primarily measures extracellular fluid, including blood and interstitial fluid.
- High Frequency (100kHz): Measures intracellular fluid, including muscle, fat, bone, and organs.
This comprehensive approach provides a more precise and detailed body composition analysis compared to traditional 4-electrode scales.

5.3. Unit Switching
The scale supports switching between kilograms (kg), pounds (lb), and stones (st). This setting can typically be adjusted within the Fitdays app or via a button on the underside of the scale, if available.
6. App Integration and Features
The Fitdays app is your central hub for all body composition data and tracking.

- Battery Replacement: When the battery indicator appears on the display or in the app, replace all 4 AAA batteries with new ones.
- Retractable Handle: Ensure the retractable data cable for the handle is not obstructed and retracts smoothly. Avoid forcing it.
8. Troubleshooting
- Scale Not Turning On: Check if the batteries are correctly installed and not depleted. Replace batteries if necessary.
- Inaccurate Readings: Ensure the scale is on a hard, flat surface. Avoid carpets or uneven floors. Make sure your feet are clean and dry, and you are standing still. Ensure the handle electrodes are properly gripped.
- App Not Connecting: Ensure Bluetooth is enabled on your smartphone and the Fitdays app is open. Try restarting both the scale (by removing and reinserting batteries) and the app.
- No Body Composition Data (Only Weight): Ensure you are stepping on the scale barefoot and holding the retractable handle with both hands, making full contact with all 8 electrodes. The app must be open and connected during the measurement.
- Error Messages: Refer to the Fitdays app for specific error code explanations or consult the manufacturer's support.
- Retractable Cable Issues: If the retractable cable for the handle does not retract properly, do not force it. Contact customer support for assistance.
