If only one L is displayed, the impedance is too low, which is beyond the measurement range. The symbol 1 is displayed when. There are water stains on the surface of the body fat scale. 2. There are metal substances on the soles. The measuring process has not been finished, so we got off the scale. 4. During the measurement, the human body or feet will shake. The symbol H of the body fat scale indicates that the impedance is too high, L indicates that the impedance is too low, lo is in a low power state, and -ERR is in an error state. I lost weight, but I didn't lose fat. Is my figure still the same? This is invisible obesity-the fat rate is at work. People with high fat rate accumulate fat in abdominal organs, which not only affects their health, but also hinders their appearance. Eat less, or get fat easily? This may be due to sedentary exercise, which leads to the decrease of skeletal muscle mass and basal metabolic rate. It takes longer exercise to reach balance. Huawei and Hefei Institute of Material Science, Chinese Academy of Sciences jointly developed Huawei TruFit human body composition detection algorithm. Based on big data and AI technology, we can measure the data of important human components such as fat and skeletal muscle more accurately, and guide a healthy lifestyle scientifically.
