Product information / Notes on use
There may be a flaw in the accuracy of the measurement if absolute quiet is not observed while the measurement is
being taken or the conditions stated are outside those parameters laid down in the specifications. See technical data.
The cuff fits at a wrist circumference of 12,5 to 21,5 centimetres.
The device covers pressures up to 300 mmHg and a pulse rate of 40 to 160 beats per minute.
Method of measurement
This product uses the oscillometric method for measuring blood pressure and pulse rate. The cover is placed round
the arm as shown on the diagram on the cuff. When the Start/Stop button is pressed, the device starts to build up
pressure automatically.
Within a very short space of time the device records the small oscillations within the cuff, which occur owing to
expansion and contraction of the arteries in the arm (pulsation). The automatic pressure build-up usually stops at
approx. 190mmHg. If the cuff pressure is too low, the device automatically increases the pressure in increments of
40mmHg. During the deflation, the cuff detects pulse waves, which are transfused to the pressure transducer in the
device chassis. Out of the amplitude of each pressure wave the values of Systole and Diastole will be calculated and
displayed. From the temporally space between the pulse waves, the pulse frequency will be calculated and displayed.
The monitor offers an additional display for identifying irregular pulses. This can be an indication of an irregular heart-
beat (arrhythmia) but also of unrest during the measurement (Irregular pulse waves).
A memory stores the last 30 results for the purposes of comparison.
