The Xiaomi Body Composition Scale S400 has a measurement accuracy error. The higher the weight is, the greater the error is.
The accuracy deviation it has is as follows:
1. 100g ≤ m < 10kg, the maximum error is 0.1kg;
2. 10kg ≤ m < 50kg, the maximum error is 0.1kg;
3. 50kg ≤ m <100kg, the maximum error is 0.2kg;
4. 100kg ≤ m ≤ 150kg, the maximum error is 0.3kg.
Deviation within the range is considered normal measurement, please feel free to use it. Due to biased loading, there will be significant deviations in real-person measurement. When weighing, it is recommended to smoothly load the scale and maintain the center of gravity in the middle of the scale body to ensure that the correct value is obtained.
