•   Remove any garment that fits closely to your upper arm.
•   Measure always 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.

4.2. 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 the arm can increase the blood pressure. Make sure you 

are in a comfortable, relaxed position and do not activate any of the muscles in the measu-
rement 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 cor rect 

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 contact your dealer. 

Note: 

Only use clinically approved

 Original-Cuffs!

•  A loose cuff or a sideways protruding air­pocket causes false measurement values.

4.3. 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 tube leaves 
the cuff on the inner side of the arm.

Important! 

The mark (ca. 3 cm long bar) must lie 

exactly over the artery which runs down the inner 
side of the arm.
