The appliance inflates
several times before
displaying the values.

This is normal if the sleeve pressure is too
low. The appliance inflates the sleeve again
until a sleeve pressure suitable for taking the
measurement has been reached.
The appliance inflates until it cannot detect
the blood pressure. If it still detects blood
pressure at the end of the inflate phase, it
continues to inflate.
The sleeve may need to be attached more
tightly.
