☞ Further Information

With each press of the button (TIME, MEMORY) one
input is made (e.g. switching over from hours to min-
utes mode, or altering the value by +1).
However, if you keep the respective button
depressed, you can switch more quickly to the
desired mode, or find the desired value respectively.

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 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 wrist (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the blood-
pressure changes during the course of the day.

5.2. Common sources of error

Note: Comparable blood-pressure measurements always require the same condi-
tions! 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
measurement arm during the measurement. Use a cushion for support if necessary.
