3. Place your arm on a tabletop or a stationary surface, with the watch screen facing up.
4. Remain still during measurement and focus on the measurement.
5. Factors such as hair, tattoo, shaking, low temperature, and incorrect wearing of the watch may
affect measurement results, and even lead to measurement failure.
6. The measurement range of the watch is 80%-100%. This feature is for reference only and
