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
The device 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. When a total failure of the instrument occurs, unplug it
and plug it back in again for a reset.
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 soft-
ware and select the sensor.
There is a 9-digit code
on the back of the sen-
sor (Fig.2). The last 4
digits of the code corre-
sponds to the last four
digits of the sensor
name in the software
(Fig.3). This allows an
exact assignment of the
sensors with the soft-
ware.
Fig. 2
Fig.3
After the sensor has been selected in measureApp, the LED
flashes green to indicate a correct connection.
If the sensor is switched on and not connected, it switches off
automatically after 5 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 sys-
tem due to the metallic sensor rod into consideration.
5.3 Replacing the battery
Remove the battery
Open the sensor by turning the screw
cap on the back of the sensor counter-
clockwise, 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".

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.
