Correct measurement posture
• For accurate measurements, wear the Watch firmly around your lower arm above the
wrist while leaving two fingers' worth of space as shown in the figure below. Also,
place your elbow on the table while positioning it close to your heart.
• Do not move and stay in the correct posture until finishing measurement.
Check the measured blood oxygen level on the screen. If your resting blood oxygen level
is between 95% and 100%, it is assumed to be within the normal range.
