For your reference, please check the following details:
1. View on the band:
After entering the [Heart rate] APP, if the band has enabled all-day heart rate monitoring, you can directly view the heart rate data by taping on the heart rate icon. After entering the [Heart rate] APP, please place your arm flat, and there will be an animation when measuring the heart rate. After the measurement is completed, the heart rate value will be displayed. You can check the current heart rate range by scrolling up the screen.
2. View on the APP:
You can view the all-day heart rate curve, the maximum/minimum heart rate, the resting heart rate, and the over-high/over-low heart rate by going to the [Mi Fitness] APP >> [Health] >> [Heart rate].
Note:
Non-standard wearing methods can affect the measurement of heart rate signals, such as light leakage caused by incomplete fitting of the band to the arm, arm swing, and slight movement of the band on the skin. Wearing the band too tightly, raising the arm, and clenching can affect blood circulation, thereby affecting blood flow and ultimately affecting heart rate signals.
