5.4. Measuring procedure
After the cuff has been appropriately positioned, themeasurement can begin:
a) Switch on the instrument by pressing the O/I-Memory button. The tube
should not yet be attached to the instrument. The following appears in
the display for 2 seconds: (Diag.)., A short be-be-beep follows to indicate
that the instrument has equilibrated with the pressure of the surround-
ings and the measurement can therefore begin. A «0» is shown in the
display.
b) Plug the T-connecting piece or the free end of the tube into the left-hand
side of the instrument.
c) Grasp the pump ball with your free hand and Inflate the cuff to a pres-
sure at least 40 mmHg higher than the expected systolic pressure. If you
do not know the value of this pressure, inflate to a value of approximate-
ly 160–180 mmHg. The cuff pressure is shown continuously on the LCD.
d) After the inflation process lay down the pump ball and remain in a quiet
and relaxed sitting position. The measurement now proceeds on its own.
If no measurement takes place and all that appears in the display is a
flashing, upwards pointing arrow, see below under «Inflate further».
When the instrument detects a pulse, a heart symbol in the display starts
to flash and a beep is heard for every heart beat.
e) When the measurement has been concluded, a long peep tone sounds.
The measured systolic and diastolic blood-pressure values as well as the
pulse frequency are now displayed. The cuff pressure can now be quickly
released by pressing the release valve at the pump ball.
5.5. Inflating further
If the cuff is not inflated sufficiently, the measurement is
broken off after a few seconds and a flashing arrow point-
ing upwards appears in the display.
It is then necessary to inflate further to at least 20 mmHg
higher than the previous value.
The instruction to inflate further can appear several times
if the pressure is still not sufficient.
Attention:
If the cuff is inflated too far (over 300 mmHg), «HI» ap-
pears in the display and a warning signal is sounded. The
cuff pressure must then be immediately released using the
quick-release valve) at the pump ball)!
As soon as the cuff is inflated sufficiently and the mea-
surement is proceeding, continue as described under
points d–e.
