Prob lem Possible
cause
Solution
Blood flow in
the skin can
be impacted
by increased
pressure on
the small
blood vessels
in the skin
(e.g. when the
watch strap is
too tight).
Try loosening the
strap a notch to
relieve some pressure,
but make sure the
watch still retains a
snug fit.
Blood flow in
the skin can
be temporarily
reduced
during warm-
up exercises
as more blood
is directed to
the muscles.
Disregard inaccurate
measures during
warm-up exercises
and provide some
time for the blood
flow to the skin
to adjust to the
exercising conditions.
Blood flow in
the skin can
be temporarily
reduced when
going outside
when it is
very cold as
more blood is
directed to the
body’s core.
Try wearing long-
sleeved clothing
to cover the watch
and starting the
measurement inside.
Disregard inaccurate
measurements during
the first couple of
minutes and provide
some time for the
blood flow to the
skin to adjust to the
exercising conditions.
Transmittance
of light through
the skin can
be influenced
by stark
contrast in
pigmentation
of the skin
(e.g. due to a
pattern in a
tattoo). This
could result
in inaccurate
optical
heart rate
measurement.
Try re-positioning the
watch at bit higher
up on the wrist or
on the other wrist
(if you place the
watch on the other
arm, do not forget
to change the watch
placement setting in
the app).
