Setup

1. Battery Installation

Open the battery compartment on the underside of the scale and insert the provided AAA batteries, ensuring correct polarity.

2. Download the Xiaomi Home App

Download the official Xiaomi Home app from your smartphone's app store (Google Play Store for Android or Apple App Store for iOS). The scale is compatible with the Xiaomi Home app but does not support Google Fit integration.

3. Pair with Your Smartphone

1. Enable Bluetooth on your smartphone.
2. Open the Xiaomi Home app and log in or create an account.
3. Tap the "+" icon to add a new device. The app should automatically detect the Xiaomi Smart Scale S400.
4. Follow the on-screen instructions to complete the pairing process.

4. Create User Profiles

Within the Xiaomi Home app, you can create individual user profiles for up to 36 people. This allows the scale to recognize different users and store their data separately. Enter details such as name, gender, height, and birthdate for each profile.

Operating Instructions

Taking a Measurement

1. Ensure the scale is on a hard, flat surface.
2. Step onto the scale barefoot, ensuring your feet are centered on the electrode pads.
3. Stand still until the measurement is complete and the display shows your weight and other metrics.
4. The data will automatically sync to the Xiaomi Home app via Bluetooth.

Multi-Weighing Modes

The Xiaomi Smart Scale S400 offers various modes for different needs:

• Standard Mode: For regular body composition analysis.
• Baby/Pet Mode: Weigh yourself first, then hold your baby or pet. The scale will calculate their weight by subtracting your weight.
• Guest Mode: For temporary users whose data you do not wish to save to a profile.

Understanding Measurements

The Xiaomi Smart Scale S400 utilizes dual-frequency Bioelectrical Impedance Analysis (BIA) to provide a comprehensive report of 25 body composition indicators. This advanced technology passes both high and low-frequency alternating currents through cell membranes to accurately measure electrical impedance values inside and outside cells, collecting detailed physical data.

Key Metrics Displayed:

• Body Weight (kg)
• Body Fat Percentage
• Heart Rate (bpm)
• Battery Level
• Bluetooth Connection Status

For a detailed report and historical data, refer to the Xiaomi Home app. The app provides a clear overview of your health status and tracks changes over time.
