Introduction
The Etekcity WiFi 8-Electrode Smart Scale is designed to provide comprehensive body composition insights. Utilizing science-backed, 8-electrode, dual-frequency technology, this scale offers detailed analysis beyond basic weight measurement. It tracks over 50 body metrics, including 5-segment measurements for fat and muscle distribution across your arms, legs, and torso. Measurements can be viewed directly on the interactive color display or through the VeSync app via Wi-Fi and Bluetooth connectivity. The scale supports multiple user profiles with automatic recognition, and features specialized modes like Guest Mode, Zero-Current Mode, and Baby Mode to accommodate various user needs.
Important Notes:
- Consult a healthcare professional before using the smart scale if you use medical electronic equipment such as a pacemaker. Alternatively, activate Zero-Current Mode to measure only weight and BMI.
- Android users may need to connect both the VeSync App and Google Fit to the Health Connect app for data synchronization.
- Body composition measurements are intended for general wellness and fitness tracking only. Results may vary based on hydration, time of day, and individual body conditions.
- Battery life of up to 3 months is based on two uses per day.
Setup
- Unpack the Scale: Carefully remove the Etekcity Smart Scale and all accessories from its packaging. Ensure you have the scale, USB Type-C charging cable, and Quick Start Guide.
- Charge the Scale: Before first use, fully charge the scale using the provided USB-C charging cable. Connect the cable to the scale's charging port and a compatible USB power source. The display will indicate charging status.
- Download the VeSync App: Download the free VeSync app from the Apple App Store or Google Play Store. Search for "VeSync".

- Placement: Place the scale on a hard, flat, and stable surface for accurate measurements. Avoid carpets or uneven flooring.

Operating Instructions
Standard Measurement
- Ensure the scale is on a hard, flat surface.
- Step onto the scale barefoot with clean, dry feet, ensuring contact with all electrode pads.
- Stand still until your weight and other body metrics are displayed on the scale's screen.
- If connected to the VeSync app, your data will automatically sync to your profile.

Using the VeSync App
- Open the VeSync app on your smartphone or tablet.
- Ensure Bluetooth or Wi-Fi is enabled and the scale is connected.
- Perform a measurement as described above. The app will display detailed metrics, trends, and reports.
- The app allows you to track progress, set goals, and integrate with other health platforms like Apple Health, Samsung Health, and MyFitnessPal.

Special Modes
- Guest Mode: Allows a user to take a quick weight measurement without saving it to a specific profile. This is useful for temporary users.
- Zero-Current Mode: Designed for individuals with medical electronic implants (e.g., pacemakers) or pregnant users. This mode disables the bioelectrical impedance analysis (BIA) function, measuring only weight and BMI to ensure safety.
- Baby Mode: To weigh an infant, first step on the scale alone. Once your weight is recorded, step off. Then, hold the baby and step back on the scale. The scale will calculate the baby's weight by subtracting your weight.
Maintenance
- Cleaning: Wipe the scale's surface with a damp cloth and a mild detergent. Avoid using abrasive cleaners, harsh chemicals, or solvents, as these can damage the surface and electrodes.
- Keep Dry: Ensure the scale remains dry. Do not immerse it in water or expose it to excessive moisture.
- Storage: Store the scale in a cool, dry place away from direct sunlight and extreme temperatures.
- Charging: Recharge the scale using the provided USB-C cable when the battery indicator shows low power. A full charge can last up to 3 months with typical usage.
Troubleshooting
| Issue | Possible Cause | Solution |
