1. Introduction
1.1. Features
The blood-pressure monitor WA-88 (with integrated time/date display) is a fully automatic, digital blo-
od-pressure measuring device for use on the wrist, which enables very fast and reliable measure ment
of the systolic and diastolic blood-pressure as well as the pulse frequency by way of the oscillometric
method of measuring.
The device offers a very high and clinical tested measurement accuracy and has been designed to
provide a maximum of user-friendliness.
Before using, please read through this instruction manual carefully and then keep it in a safe place. For
further questions on the subject of blood-pressure and its measurement, please contact your doctor.
Attention!
1.2. Important information about self-measurement
Do not forget: self-measurement means control, not diagnosis or treatment. Unusual values must Do not forget: self-measurement means control, not diagnosis or treatment. Unusual values must
always be discussed with your doctor. Under no circumstances should you alter the dosages of
any drugs prescribed by your doctor.
The pulse display is not suitable for checking the frequency of heart pacemakers! The pulse display is not suitable for checking the frequency of heart pacemakers!
In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only

be evaluated after consultation with the doctor.
Electromagnetic interference.
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong electrical
or electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave cookers).
These can lead to temporary impairment of the measuring accuracy.

2.1. How does high/low blood-pressure arise?
The level of blood-pressure is determined in a part of the brain, the so-called circulatory centre, and
adapted to the respective situation by way of feedback via the nervous system.
To adjust the blood-pressure, the strength and frequency of the heart (Pulse), as well as the width of circ-
ulatory blood vessels is altered. The latter is effected by way of fine muscles in the blood-vessel walls.
The level of arterial blood-pressure changes periodically during the heart activity: during the «blood
ejection» (Systole) the value is maximal (systolic blood-pressure value), at the end of the heart’s «rest
period» (Diastole) minimal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in order to prevent particular diseases.
