5.2. Common sources of error:
Note: Comparable blood pressure measurements always require the same conditions! Condi-
tions 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 mus-
cles 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 15cm (6 inch) 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 permis-
sible range is printed on the cuff. If this is not suitable for your use, please
call 1-800-232-2670.
Note: Only use approved ADC® cuffs!
A loose cuff or a sideways protruding air pocket causes false measure-•
ment 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. If you decide to take
your Averaging Mode measurement again, be sure to wait at least one
minute beforehand.
5.3. Fitting the rigid Cuff (6023 model only)
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 1/2” to 3/4” (1 to 2 cm) above the elbow.
Important! The red strip 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 cir-
cumference if you are not sure of proper fit.
e) Lay your arm on a table (palm upward) so the cuff is at the same height
as your heart. Make sure the tube is not kinked.
f) Remain seated quietly for at least two minutes before you begin the meas-
urement.
Fitting the D-Bar Cuff (6021, 6022 models)
a) Pass the end of the cuff through the flat metal ring so that a loop is formed.
