Operation of the device
3. Measuring in the lying position
Lie down on your back. Place the device
round your wrist and keep it at heart level,
supported by a cushion for example. To relax
before measurement, take a deep breath 5
or 6 times. During measurement it is impor-
tant to keep your arm still and refrain from
talking.
If the cuff is lower or higher than heart level,
the measured value will tend to be higher or
lower as the case may be.
Do not bend your wrist! Correct measure-
ments can only be obtained if the wrist is
at heart level. If the wrist is too high or too
low, it will lead to false results.
