Cuff (1-tube cuff + T-connector):
Insert the cuff tube into the opening provided

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 factors inflence
the measurement result. Try to find time to relax by sitting in an armchair in a quiet atmosphere 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 comfortable,
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 arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood pressure 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 ex-
traordinary 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 contact 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.
