You should always be seated and calm before and during me-
asurement.
• Avoid eating and smoking as well as all forms of exertion directly
before measurement. These factors influence the measurement
result. Find time to relax by sitting in an armchair in a quiet atmo-
sphere for about ten minutes before taking a measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Always compare measurements taken at the same time of day,
since blood pressure changes during the course of the day, as
much as 20-40 mmHg.
Comparable blood pressure measurements always require the
same conditions!
• Conditions should always be quiet.
• All efforts by the user to support the 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 lies considerably lower or higher than the heart,
an erroneously high or low blood pressure will be measured! Each
25-30cm difference in height between your heart and the cuff
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 extremely important. Cuff
size is dependent upon the circumference of the arm (measured
in the center). The permissible range is printed on the cuff.
Cuff works under the pressure range 0-300MMHG
The wide range rigid cuff is: 8.7” – 15.7” (22 - 40 cm)
Only use approved cuffs!
• A loose cuff or a sideways protruding air pocket causes false me-
asurement values.
