How to do if Mi Body Composition Scales always measure body fat failed?

Problem Explanation
It may be due to:
1. The age and height set in the APP are not within the range of body fat measurement:
Age range: 6 ~99 years old
Height: 90cm~220cm
2. The surface of the metal electrode of Mi Body Composition Scales is contaminated or the soles of the feet are relatively dry. It is suggested to clean the surface of the metal electrode of Mi Body Composition Scales or the soles of the feet with a wet towel before measurement;
3. The contact between the sole of foot and the metal sheet on the surface of the scale is not correct, it is necessary to step on the metal sheet barefoot, and the two feet are naturally distributed on both sides of the scale;
4. When it weighs, steps off the scale without waiting for the body fat data measurement (the weight value on the display screen flashes twice and enters the fat measurement process; it is suggested to step off after completing measurement.)
