• Please use «AAA» Long-Life or Alkaline 1.5 V Batteries. The use of 1.2 V Accumulators is not recommended.
• If the blood pressure monitor is left unused for long periods, please remove the batteries from the device.
Functional check: Press and hold the O/I button down to test all the
display elements. When functioning correctly all segments appear.
4.2.Tube connection
Cuff (1-tube cuff + T-connector):
Insert the cuff tube into the opening provided on the back
of the instrument, as shown in the diagram.
5. Carrying out a measurement
5.1.Before the measurement
• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these fac-
tors influence the measurement result. Try to find time to relax by sitting in an armchair in a quiet at-
mosphere for about 5 minutes before measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the 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!
These are normally always quiet conditions.
• All efforts by the patient to support their arm can increase blood pressure. Make sure you are in a com-
fortable, relaxed position and do not activate any of the muscles in the measurement arm during the
measurement. Use a cushion for support if necessary.
• If the wrist artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood pres-
sure will be measured! (Each 15 cm difference in height results in a measurement error of 10 mmHg!)
• Cuffs that are too narrow or too short result in false measurement values. Selecting the correct cuff is
of extraordinary importance. The cuff size is dependent upon the circumference of the arm (measured in
the centre). The permissible range is printed on the cuff. If this is not suitable for your use, please con-
tact your dealer. Note: Only use clinically approved Original-Cuffs!
• A loose cuff or a sideways protruding air-pocket causes false measurement values.
5.3.Fitting the cuff
a) Push the cuff over the left upper arm so that the tube
points in the direction of the lower arm.
b) Lay the cuff on the arm as illustrated. Make certain
that the lower edge of the cuff lies approximately 2 to
3 cm above the elbow and that the rubber tube leaves
the cuff on the inner side of the arm.
Important! The mark (ca. 3 cm long bar) must lie over
the artery which runs down the inner side of the arm.
