SAFETY PRECAUTIONS
Caution!
-
Carefully read these operating instructions completely before operating this instrument. This is necessary to avoid damage to it, as well as for user safety.
-
Only use the instrument for the purpose for which it was designed.
-
Only use the instrument in dry rooms in which there is no risk of explosion.
-
Protect the instrument from dust, moisture, and vapors.
Use a slightly moist lint-free cloth to clean the instrument.
Do not use aggressive cleaning agents or solvents. -
Take care that no liquid penetrates in through the housing openings, as such penetration would result in damage to Sensor.
-
Do not open the unit.
PURPOSE AND CHARACTERISTICS
The sensor is used for measuring the respiratory volume and volumetric flow
rate and for transferring the values to a terminal device, e.g. a tablet
computer, smartphone, etc., via Bluetooth or USB. The sensor is neither
suitable nor approved for medical purposes.
It is intended solely for didactic purposes. This device must not be used for
defined measurements on humans in order to diagnose an illness or disease,
i.e. it is not intended for monitoring, treating, or alleviating illnesses or
diseases. As a consequence, it is not subject to the strict constraints of the
Medical Devices Act.
FUNCTIONAL AND OPERATING ELEMENTS
3.1 Operating elements
The sensor has an on-button and two LEDs for indicating the Bluetooth and
battery charge status.
On-button
To switch the sensor on and off in Bluetooth mode, the power button must be
pressed for longer than 3s. If the sensor is to be connected via USB, it is
not necessary to press the power button.
Bluetooth-LED
| Flashing red every 2 seconds | Not connected |
|---|---|
| Flashing green every 2 seconds | Connected to the terminal device |
| Flashing green every 4 seconds | Running measurement |
Battery charge LED
| Flashing red every 2 seconds | Low battery |
|---|---|
| Illuminated red | Active charging process |
| Illuminated red | Charging process completed |
3.2 USB port
The battery, which is permanently installed in the sensor, is charged via the
type C USB port. Furthermore, communication with a computer takes place via
this interface.
3.3 Functional elements
On the front side, there is a BNC connector for connecting the Geiger-Müller
counter tube.
NOTES ON OPERATION
This device fulfills all of the technical requirements that are compiled in
current EC guidelines. The characteristics of this product qualify it for the
CE mark. The individual connecting leads are each not to be longer than 2 m.
The instrument can be so influenced by electrostatic charges and other
electromagnetic phenomena (HF, bursts, indirect lightning discharges) that it
no longer works within the given specifications. Carry out the following
measures to reduce or eliminate the effect of such disturbance: Ensure
potential equalization at the PC (especially with Laptops). Use screening. Do
not operate high-frequency emitters (e.g. radio equipment or mobile
radiotelephones) in the immediate vicinity. When a total failure of the
instrument occurs, unplug it and plug it back in again for a reset.
HANDLING
This section describes the start-up of the sensor and the recording of
measurement data. Please read this section thoroughly in order to avoid
failures or operating errors.
5.1 Start-up
Switch on the sensor by pressing the power button for more than 3s. Now the
Bluetooth LED flashes red. Start the software and select the sensor. If the
sensor is to be used via the USB interface, it does not need to be switched
on. The sensor is connected directly to the end device using the supplied USB
cable.
There is a 9-digit code on the back of the sensor (Fig.2). The last 4 digits
of the code are displayed as the sensor name in the software (Fig.3). This
enables the precise assignment of the sensors within 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 software 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 established 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 displayed. It can be selected and connected
directly.
5.2 Radiation measurement data
Connect the Geiger-Müller counter tube (included in delivery) to the front BNC
socket of the sensor.
The ionizing particles of the alpha, beta, or gamma radiation trigger a
current pulse in the Geiger-Müller counter tube, which is registered by the
sensor. With the aid of measure app, the pulses or the resulting pulse rate
are displayed.
5.3 Charging process
Use a USB-C cable to connect the sensor to a computer or USB charger (not
included).
During the charging process, the battery charge LED lights up red. When the
charging process is complete, the battery charge LED lights up green. The
charging time for a completely discharged battery is 3 hours maximum.
Disconnect the charger at the latest four hours after the completion of the
charging process. Otherwise, the service life of the battery may be negatively
affected.
