been replaced.

vice.

display elements. When functioning correctly many icons will

3. Measurement Procedure
ATTeNTION
• Find time to relax by sitting in a quiet atmosphere for some
time before measurement.
• Efforts by the patient to support the arm can increase the
blood pressure. Make sure you are in a comfortable, relaxed
position and do not activate any muscles in the arm during
measurement.
• Always measure on the same arm (normally left).
• Remove any garment that fits closely to your upper arm. Do
not roll the sleeve since it can squeeze your hand and this can
lead to false results.
• Use only clinically approved original cuff
• If you want to follow the results of your blood pressure meas-
urements, always perform measurements at the same time of
day, since blood pressure changes during the course of the
day.
• Measurements should be done after a 5 minute rest to ensure
accuracy.
