4. Tighten the cuff by pulling the end and
close the cuff by affixing the velcro. There
should be little free space between the arm
and the cuff. Cuff that does not fit properly
results in false measurement values. Cloth-
ing must not restrict the arm. Any piece of
clothing which does must be removed.
5. Lay your arm on a table so the cuff is at
the same height as your heart. If the upper
arm artery lies considerably lower or higher
than the heart, a false higher or lower blood
pressure will be measured! A variation of 15
cm between cuff and heart level can result in
a reading error of + or - 10mm Hg.
Make sure the tube is not kinked.
6. Remain seated quietly for two minutes
before you begin the measurement.
3.2. Measuring procedure
To carry out measurement
1. Press the START button. The built-in
microprocessor begins to inflate the cuff. In
the display, the increasing cuff pressure is
continually displayed.
2. After automatically reaching an in-
dividual pressure, the pump stops and the
pressure slowly falls. The cuff pressure is dis-
played during the measurement. When the
device has detected your pulse, the heart
symbol in the display begins to blink and a
beep tone is audible for every pulse beat.
