5.3 Start-up
Switch the sensor on by pressing the on-button for more than
3 seconds. The Bluetooth LED lights up red. Start the soft-
ware and select the sensor.
A
9-digit
code
is
printed on the back of
the
sensor
(Fig.6).
The last 4 digits of the
code are displayed as
sensor designation in
the software (Fig.7).
This enables an exact
assignment
of
the
sensors
with
the
software.

Selection of the sensor via the Bluetooth interface
Make sure that the Bluetooth interface is activated on the
terminal device (PC/Tablet/Smartphone) and that the soft-
ware is allowed to access the interface.
After the sensor has been selected in the software, the LED
flashes green to indicate that the connection has been estab-
lished correctly. After the sensor has been coupled with the
software, the sensor is no longer visible to other users in the
software, and therefore can no longer be selected.
If the sensor is switched on and not connected, it switches off
automatically after 5 minutes.
Selection of the sensor via the USB interface
For this purpose the sensor must be plugged into the USB
port of the end device. It is not necessary to switch on the
sensor. The sensor is automatically recognized and dis-
played. It can be selected and connected directly.
5.4 Recording of measurement data
Press the bellows (fig.2 no.2) quickly and repeatedly until a
pressure of 150-170 mmHg is reached. Start the measure-
ment in the software and now slowly open the release valve
(fig.2 no.3) until the pressure is continuously reduced slightly.
If the pressure has fallen below 50 mmHg stop the meas-
urement and open the release valve completely
.
Fig. 8
The pulse pressure signal (∆p) superimposed on the falling
pressure is normalised to 1.0 at its maximum amplitude
(MAP).
The systolic pressure (SAP) is on the falling pressure curve
at the point where ∆p has an amplitude of 0.5 (before MAP).
Diastolic pressure (DAP) is normalised to 0.85 (after MAP) on
the falling pressure curve at the point where ∆p has fallen to
the amplitude of 0.85 (after MAP).
