7.4. Communication test
A simple test will check the communication channel between sensor and
receiver:
1.
Remove the batteries from the sensor
2.
If an entry already exists: remove the sensor from the
temperatur logger application (using the right mouse button)
3.
Locate the sensor at ca. 1 m distance to the receiver
4.
Insert the batteries in the sensor
5.
A correctly working system will add the according sensor entry
to the sensor list within 5 seconds.
7.5. Battery
The BS1200 has a 3V Li CR2032 coin cell battery for powering the real time
clock and the settings memory during power down. We advise to replace
the battery every 3 years. Actual lifetime of the battery depends on ope-
rating. When the BS1200 is powered on continuously, then a battery life of
over 10-15 years can be expected.
Fig.4. The coin battery cell is located at the
centre of the circuit board of the BS1000.
The BS1200 starts logging as soon as
the BS1200 is powered on. No further
requirements are necessary. The first time use or when the coin battery was
removed: Then the clock must be set, before logging can start. This can be
done via the USB port, connected to the temperature logger software, or by
a remote time server via the network.
