If there's a discrepancy in the heart rate data, it might be due to incorrect or non-standard wearing of your device, such as the strap being too tight or too loose, or moving your arm during the measurement.
Proper Measurement Method: Keep your arm flat, relaxed and still, and make sure the wristband fits snugly around your wrist.
Note: Heart rate data is for reference only and should not be used for medical diagnosis.
Please tear off the plastic film on the sensor on the back of the watch before measuring to avoid affecting the reflectivity and causing data deviation.
