PURPOSE AND CHARACTERISTICS
The Cobra4 Mobile-Link 2 is used for the mobile acquisition
of measurement values that are generated by way of a Co-
bra4 Sensor-Unit.
For this purpose, the unit is equipped with an SD/MMC
memory card. The control menu of the unit enables all rele-
vant adaptations, e.g. the calibration and taring of the unit,
without the need for a PC.
In order to transfer the data to the PC after the completion of
the measurement, the Cobra4 Mobile-Link 2 is equipped with
a USB socket. As an alternative, the memory card can be
removed and the data can be transferred to a PC by way of a
reading device. Ensure that no other Cobra4 device is con-
nected to the PC during the data transfer.
The power supply of the Mobile-Link 2 is ensured by an inte-
grated, rechargeable lithium-ion battery with a charge of
1950
mAh. Due to its technology, it exhibits a certain, mini-
mum level of self-discharge. This is why we recommend
checking the charge of the battery prior to using the device,
and to recharge it if necessary.
The battery can be charged via a computer by way of a USB
cable or by way of the supplied power supply unit.

FUNCTIONAL AND OPERATING ELEMENTS
3.1
Operating elements on the top
The Cobra4 Mobile-Link 2 is equipped with various elements
for the measurement data display, operation, and status
indication. These elements are explained in detail in the
following sections (Fig. 2).
1.
ON/OFF switch
For switching the unit on and off. The process of
switching the unit on or off is confirmed by way of a
sound signal (brief beeping sound). The unit has an
automatic switch-off function in order to prevent the
battery from being discharged: If no measurement is
performed, the unit will be switched off ten minutes af-
ter the last actuation of a button. If the voltage falls be-
low a critical level during the measurement data re-
cording process, an audible alarm will be issued and
the unit will save the measurement values that have
been recorded up to this moment. Then, the unit will
switch off.
2.
Display
Colour representation of the measurement values and
selection elements for the menu navigation.
3.
LED
Battery
For indicating the battery charging process. The LED
lights when a power supply unit or USB cable is con-
nected.
4.
Navigation arrows
For selecting a specific measurement
value in the case of multi-channel sen-
sors and for the menu navigation.
5.
Confirmation key
For starting and stopping the measurement data re-
cording process and for the menu navigation.
3.2
Sensor interface
The front of the unit is equipped with an interface via which
the connection to a corresponding Cobra4 Sensor-Unit is
realised. This mechanically secure connection is made by
way of lock knobs and holes on/in both units (Fig. 3).
