1 SAFETY PRECAUTIONS
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 vapours.
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 hous-
ing openings, as such penetration would result in dam-
age to Sensor.
Do not open the unit.
2 PURPOSE AND CHARACTERISTICS
The sensor is used for measuring temperature values and for
transferring the values to a terminal device, e.g. a tablet
computer, smartphone, etc., via Bluetooth.
Caution!

4 NOTES ON OPERATION
This Cobra SMARTsense Wide Range Temperature fulfils all
of the technical requirements that are compiled in current EC
guidelines. The characteristics of this product qualify it for the
CE mark.
This instrument is only to be put into operation under special-
ist supervision in a controlled electromagnetic environment in
research, educational and training facilities (schools, universi-
ties, institutes and laboratories).
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 screen-
ing.
5 HANDLING
This section describes the start-up of the sensor and the re-
cording of measurement data. Please read this section thor-
oughly in order to avoid failures or operating errors.
5.1 Start-up
Switch the sensor on by pressing the on-button for more than
3 seconds. The Bluetooth LED lights up red. Start the
measureApp application and select the sensor.
There is a four-digit code on the back of the sensor. This
code corresponds to the last four digits of the sensor name in
the measureApp application. This enables the precise as-
signment of the sensors within the measureApp application.
After the sensor has been selected in the measureApp appli-
cation, the LED lights up green, thereby signalling that the
connection has been correctly established.
If the sensor is switched on, but not connected, it will switch
off automatically after five minutes.
5.2 Recording of temperature measurement data
Hold the sensor into the medium to be measured down to a
maximum depth of 15 cm.
Take the response time of the system due to the metallic
sensor rod into consideration.
5.3 Remove the battery
Open the sensor by turning the screw cap
on the back of the sensor counterclock-
wise, e.g. with a coin.
Fig. 4
Lever the battery sensitively,
e.g. with the help of a small
screwdriver or a small pair of
scissors, out of its socket. In-
sert the screwdriver as shown
in Fig. 5.
Fig. 5
Insert new battery
Slide the battery under the golden metal nose (Fig.6-1). Make
sure that the battery is completely under the metal nose and
completely pushed to the upper edge.
Push the battery into the socket
by pressing lightly on the oppo-
site side.
The battery slips under the two
plastic lugs (Fig. 6-2), which is
also noticed by a short "click".
Fig. 6
Before closing, make sure that
the seal in the lid is not bent and
lies neatly on the edge of the lid.
Then tighten the cover clock-
wise.
