B. Fasten the pressure cuff snugly.
a Close the cuff with the Velcro
fastener, so that the top margin
of the computer is about 10 mm
below the ball of the thumb.
b Do not pull strongly on
the pressure cuff. Do not make
the pressure cuff too tight.
7. Correct measurement position
lt is extremely important for the measured values, that the cuff is at
the same height of the heart. Higher or deeper position will give devi-
ations from the true value.
Measurement while sitting down:
a Place your elbow on a table or other
object.
b Use the armrest to position the arm so
that the pressure cuff is at the same
height as the heart.
c Relax your hand with the palm facing
up. Do not talking or moving during
measurement.
