4.3. Tube connection

Insert the cuff tube into the opening provided on the left side of the
instrument, as shown in the diagram.

4.4 Setup time and date

The blood-pressure monitor stores time and date for every measu-
rement. This is a very important information because the blood pres-
sure normally changes during the day.
After insertion of new batteries you have to enter the actual date and
time. Therefore push the CLOCK-Button for at least 3 seconds. The
display shows now the year setup with 4 flashing numbers. By pus-
hing the MEMORY-Button you can enter the actual year.
HINT: This action is fastened if you keep the button pressed.
If you push the CLOCK-Button your entry is confirmed and you attain
the next setup step.
Repeat this procedure until you have adjusted all entries (year,
month, day, time). After that the clock starts working automatically.

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 influence the mea-
surement result. Try and find time to relax by sitting in an
armchair in a quite atmosphere for about 5 minutes before the
measurement.
• 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 cour-
se 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 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 sup-
port if necessary.
• If the arm artery lies considerably lower (higher) than the
heart, an erroneously higher (lower) bloodpressure will be
measured! (Each 15cm difference in height results in a mea-
surement error of10mmHg!)
