Problem Possible cause Solution
In doubt about
accuracy. /
My device is
not measuring
correctly.
Direct contact with the skin
can be lost if e.g. the watch
is worn too loosely, when
the strap is positioned over
the wrist bone or when
there is a lot of hand/wrist
movement.
Make sure to position the watch
correctly (see 'Wearing the health
watch') and provide a snug but
comfortable fit. If this does not fix
the issue, try re-positioning the
watch at bit higher up on the arm
or on the other arm. (if you place
the watch on the other arm, do
not forget to change the watch
placement setting in the app).
