•
Inaccurate measurements occur when the device is loose
and the light used to provide the measurement is reflected
unevenly.
•
If the measurement is very different from the expected heart
rate, rest for 30 minutes and then measure it again.
•
During winter or in cold weather, keep yourself warm when
measuring your heart rate.
•
Smoking or consuming alcohol before taking measurements
may cause your heart rate to be different from your normal
heart rate.
•
Do not talk, yawn, or breathe deeply while taking heart rate
measurements. Doing so may cause your heart rate to be
recorded inaccurately.
•
If your heart rate is extremely high or low, measurements
may be inaccurate.
•
Heart rate measurements taken for infants and toddlers may
be inaccurate.
•
Do not look directly at the heart rate sensor's lights. Doing
so may impair your vision.
