pulse result only.

5. Measurement Procedure

--------------------------------------------------------------------------------------------------------------------

Note: You should always be seated and calm before and during measurement.

5.1. Before measurement:

• 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

atmosphere 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.

5.2. Common sources of error:

Note: 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 0-299mmHg

The wide range rigid cuff is : 9.1" – 14.2" (23-36 cm)

• 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. Consecutive

blood pressure measurements should be repeated after a 1 minute pause or after your arm has been held

up in order to allow the accumulated blood to flow away.

5.3. Fitting the Cuff

Please refer to picture-06

a) The cuff is pre-formed for easier use. Remove tight or bulky clothing from your upper arm.

b) Wrap the cuff around your upper left arm. The rubber tube should be on the inside of your arm extending

downward to your hand. Make certain the cuff lies approximately 0.39" to 0.79" (1 to 2 cm) above the elbow.

Important! The red mark on the edge of the cuff (Artery Mark) must lie over the artery which runs down the

inner side of the arm.

c) To secure the cuff, wrap it around your arm and press the hook and loop closure together.

d) There should be little free space between your arm and the cuff. You should be able to fit 2 fingers

between your arm and the cuff. Cuffs that don't fit properly result in false measurement values. Measure your

arm circumference if you are not sure of proper fit.
