Optical heart rate measurement from the wrist is an easy and
convenient way to track your heart rate. To get the best results, please
keep in mind factors that may affect heart rate measurement:
• The watch must be worn directly against your skin. No clothing,
however thin, can be between the sensor and your skin.
•
The watch may need to be higher on your arm than where
watches are normally worn. The sensor reads blood flow
through tissue. The more tissue it can read, the better.
•
Arm movements and flexing muscles, such as gripping a tennis
racket, can change the accuracy of the sensor readings.
• When your heart rate is low, the sensor may not be able to
provide stable readings. A short warm up of a few minutes
before you start the recording helps.
• Darker skinned individuals may not get reliable readings from
the optical sensor.
• For highest accuracy and quickest responses to changes in
you heart rate, we recommend using a compatible chest heart
rate sesnor such as Suunto Smart Sensor.
