The introduction is as follows.
Wear the strip about one finger away from the wrist bone, and adjust the tightness of the strip to a comfortable position to ensure that the heart rate sensor can collect data normally.
For the heart rate sensor to measure optimally, the back of the band needs to be in contact with the skin. Fit the strip properly, neither too tight nor too loose, while allowing room for the skin to breathe. The wrist strap of the strip can be tightened during exercise, and then loosened after exercise.
