Further Information
With each press of the button (TIME, MEMORY) one input is made (e. g. switching
over from hours to minutes mode, or altering the value by +1). However, if you
keep the MEMORY button depressed, you can switch more quickly to find the de-
sired value respectively.
5 MEASUREMENT PROCEDURE
5.1. MEASUREMENT PREPARATION
• Avoid eating, smoking as well as all forms of exertion directly before the
measurement. All these factors influence the measurement result. Try and
find time to relax by sitting in an armchair in a quite atmosphere for about
ten minutes before the measurement.
• Measure always on the same arm (normally left).
• Try to carry out measurements regularly at the same time of the day, since
the blood pressure level changes during the course of the day.
5.2. COMMON SOURCES OF ERROR
NOTE
Comparable blood pressure measurements always require the same
conditions. In a state of physical and emotional rest.
• Take a comfortable position, relax and do not toughen muscles of the arm
subject to measurements. If necessary, use a cushion for support.
The performance of an automatic sphygmomanometer can be influenced
by extreme environmental conditions: high or low temperature, humidity,
elevation of the measurement point above sea level.
• Prevent deformation and twisting of the cuff tube.
• Improper (loose) fixation of the cuff on the arm causes false measurement
values.
