At present, the normal range of heart rate measurement of watches is 40 ~ 220 beats/min. If your heart rate is lower than 40 beats per minute or higher than 220 beats per minute, the watch will prompt you on the interface.
Heart rate warning prompt:
The daily heart rate is monitored when you are in a quiet state, and the default continuous 10 minute heart rate value exceeds 120 beats/minute (mobile phone equipment >); More > this value can be modified in sports health settings), and a notification will pop up to remind you.
Exercise heart rate warning is a reminder that will pop up when your real-time heart rate exceeds your maximum heart rate (220- your age) after you turn on the exercise function of each watch. The maximum heart rate is calculated according to your age.
View heart rate history data:
When the watch is normally connected to the mobile phone, open the "Health" APP of the mobile phone to enter the home page, and click the heart rate card to view the historical heart rate data.
