Function Explanation：
Yes, Mi Band supports Pressure Detection, it can manually measure pressure or open pressure automatic detection throughout the day.
1.Manual measurement method:The pressure detail page of the bracelet can measure the current pressure value. In the case of successful measurement, the current pressure value will be displayed.To ensure the success of the measurement, please wear the bracelet correctly and keep still during the measurement.
2. Open the page of heart rate detection on the APP terminal and start the pressure detection. The band will automatically measure the pressure of the body in a quiet state.To enable pressure detection, enable the all-day heart rate detection function.
Setting Path:
1. Mi Fit App-> My-> Mi Band-> Heart Rate Detection -> Pressure Detection
2. MI Wear App-> Device->Additional Setting -> Heart Rate Detection -> Pressure Detection
View Path:
1. When the pressure measurement page has measured data, the pressure status can be viewed by sliding down.
2. Check the history of pressure testing on the Mi Fit APP.
3. Check the pressure information in the data page of Mi wear APP.
Stress: Stress here specifically refers to mental stress, not including the physical stress caused by high-intensity exercise.Pressure testing principle is the use of heart rate variability to assess the current pressure strength, the current heart rate variability and personal data in sleep, relaxation time of heart rate variability were compared, and combining with personal body activity trace to the auxiliary judgment, when in low intensity physical activity, if the heart rate variability was significantly weaker, means that the current under the spirit of the high strength pressure.
Note：
1. Please wear the device correctly and turn on the pressure detection to ensure that the heart rate monitoring data during the pressure monitoring process is normal.
2. What the equipment detects is the daily pressure value, and the pressure will be detected only in the static state for a long time. If it is in the non-static and moving state, the equipment may not have the pressure value.
3. In the bar chart of recent pressure values, it is normal that some pressure values are missing. It may because of a non-static state for most of the time during this period of time, and the accuracy of pressure data evaluation will be affected to a certain extent (during intense exercise or frequent medium-high intensity activities).
4. If the above situation is not, and the pressure value is still not available, the pressure detection can be carried out by wearing it during sleep at night.
5. The band is not a medical device. The test results and suggestions are for reference.
