zInfluences on measuring
accuracy
Wearing the product incorrectly causes
measurement errors:
Strap nice and tight on
wrist
Too loose
Adjust the product’s strap so that the product
sits correctly around your wrist.
Search for the heart rate signal again.
Optical heart rate measuring: The
product measures your heart rate at your wrist,
using an optical sensor. A chest belt is not
required when using this method.
Blood circulation: Blood circulation varies
from person to person and may differ intra-
individually (for example, between the left and
right arms). In some cases, natural blood flow
may not be optimal for heart rate measurement
with an optical sensor in certain individuals.
Environmental factors: If the ambient
temperature is too low, blood flow to the
forearms can be reduced and this may reduce
measurement accuracy.
Skin colour: Skin reflectivity is influenced
by the colour of the skin surface. The less
light is absorbed through the skin surface, the
better the heart rate measurement. Strong
pigmentation of the skin, scarring and tattooing
can therefore adversely affect the measurement
accuracy.
Keep skin dry and clean: It is important
to keep the product and your skin clean and
dry. This will maximize comfort and prevent
damage to the product.
This is especially important during workouts
or exposure to liquids. Liquids such as sweat,
soap, sunscreen, and lotions can reduce
measurement accuracy.
Posture: Improper posture (such as
sharply bent wrists) affects the circulation
of the forearms and reduces the heart rate
measurement accuracy.
