• If your blood pressure monitor is not used for
long periods, please remove the batteries from
the device.
Functional check:
Hold on the on/off button down to test all the
display elements. When functioning correctly icons
will appear.
4.2. Tube connection

Cuff
Set up (or check) the tube connections between
cuff, instrument and pump ball as shown in the
diagram.
5. Taking a measurement
5.1. Before a measurement:
• Avoid eating, smoking as well as all forms of exertion directly before a measurement. All
these factors influence the measurement result. Relax by sitting in an armchair in a quiet
atmosphere for about ten minutes before a measurement.
• Remove clothes that fit closely to your upper arm.
• Always measure on the same arm (normally left).
• Take measurements at the same time of day, since blood pressure changes during the course
of the day.
5.2. Common sources of error:
Note:
Comparable blood pressure measurements always require the same conditions!
(quiet conditions).
• Supporting your arm can increase blood pressure. Make sure you are in a comfortable,
relaxed position and do not flex any of the muscles in the measurement arm during the
measurement. Use a cushion for support if necessary.
• If the arm artery cuff is considerably lower or higher than the heart, an erroneously higher or
lower blood pressure will be measured! (Each 15 cm difference in height results in a
measurement error of 10 mmHg!)
• Selecting the correct cuff size is of extraordinary importance. The cuff size is dependent upon
the circumference of the arm (measured in the center). The permissible range is printed on
the cuff. If your cuff does not fit properly, contact microlife.
Note:
Only use clinically approved
microlife cuffs!
• A loose cuff or a sideways protruding air-pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Correctly executed blood pressure measurements should be repeated after a
1 minute
pause.
