Q:
How
to
get
more
accurate
heart
rate,
blood
pressure,
blood
oxygen
A:
The
light
‐
emitting
position
of
the
watch
should
be
close
to
the
skin
to
ensure
that
there
will
be
no
significant
position
shift
during
exercise.
Too
loose
or
tight
during
wearing
will
affect
the
test
results
(to
avoid
light
leakage,
the
skin
epidermis
position
moves
when
light
is
reflected
Wait)
;
The
light
‐
emitting
position
of
the
watch
should
not
be
close
to
the
protruding
bones
(radius
and
ulna)
on
the
wrist
side,
otherwise
the
watch
cannot
receive
the
red
light
reflected
by
the
blood
vessels
correctly,
which
will
affect
the
test
results;
To
pursue
a
more
accurate
heart
rate
value,
you
can
wear
the
watch
to
the
arm
position
on
the
wrist.

Q:
Why
is
the
watch's
accounting
step
inaccurate
A:
When
setting
up
for
the
first
time,
fill
in
the
information
of
gender,
age,
height,
and
weight
honestly
and
accurately.
These
inaccuracies
will
affect
the
calculation
of
the
accelerometer
algorithm,
resulting
in
inaccurate
step
counting,
incorrect
distance
data,
and
inaccurate
calorie
consumption.
So
as
to
get
unsatisfactory
data,
which
affects
your
personal
exercise
number;
The
pedometer
data
is
obtained
for
data
analysis
of
acceleration
in
three
directions,
so
the
wearing
situation
of
the
watch
also
has
a
certain
influence
on
the
accuracy
of
the
result.
It
is
necessary
to
ensure
that
the
watch
will
not
move
in
the
wearing
position
(left,
right,
up
and
down)
during
exercise;
In
addition,
the
user's
arm
swing
posture,
stride
length,
body
shape,
road
surface
flatness,
uphill
and
downhill
will
also
affect
the
step
count;
If
the
body
moves
during
sleep
(possibility
factors
such
as
turning
to
the
side
during
sleep,
getting
up
and
then
falling
asleep
in
the
middle
of
the
sleep),
in
a
car
or
driving,
such
as
uneven
roads
and
bumps,
it
is
possible
to
produce
steps.
