Ensuring Accurate Measurements
Heart rate readings may be inaccurate depending on conditions and
surroundings. Follow these steps for more accurate heart rate readings:
Never measure your heart rate after smoking or drinking alcohol.
•
Smoking and/or alcohol can affect your heart rate.
Never take heart rate measurements at low temperatures. Keep
•
yourself warm when you measure your heart rate.
Users with thin wrists may find their heart rate measurements are
•
inaccurate.
When measuring your pulse for workout purposes, take the
•
measurement while seated and relaxed before exercise, then proceed
with your workout.
If the measurement significantly differs from predicted values, relax
•
and measure again in 30 minutes.
Confirm your pulse by taking the average of around 5 repeated
•
measurements.
If you speak, yawn or breathe deeply during the measurement, you
•
may see inaccurate values.
Light reflection may be uneven depending on your circulation, blood
•
pressure or skin condition, and may lead to inaccurate measurements.
If light reflection is blocked by body hair or other items, you may
•
obtain inaccurate measurements.
If the heart rate sensor is dirty, wipe the sensor and try again for a
•
more accurate measurement.
