3. Follow the instructions.
4. Apply the gas from the test gas cylinder
(1)
with the gas supply adapter
(2)
to the sensor with a minimum of 0.5 L/min.
✓
The calibration is performed as soon as the sensor signal is stable or the
maximum calibration time has expired. The maximum calibration time
depends on the sensor type used (e.g. CO 6809605 3 min., NH3 6813735
5 min.).

Maintenance
The sensing head and the LoRa gateway do not require maintenance. The
service life of the used sensor depends on the sensor type. When the sensor is
taken out of the sensing head, the measurement system switches into the
power-save mode. Further information about the sensor can be found in the
respective sensor data sheet.
9.1
Maintenance
Observe the charge status of the internal rechargeable battery. Carry out a daily
visual inspection to check the operational readiness. Have specialists carry out
an annual device inspection and sensor calibration.
CAUTION
Health hazard
The dust filter in front of the sensor must not be contaminated. A contaminated
filter prolongs the response time of the sensor. This affects the sensitivity.
► Replace the contaminated filter.
9.2
Cleaning
Clean the sensing head surface with lukewarm water. Check for mechanical
damage.
CAUTION
The sensing head may be damaged
The sensing head must not be present when the area of use is cleaned and
disinfected.
► Remove the sensing head from the area of use.
10
Transport
CAUTION
Risk of damage to the sensor
The sensor must be packed in pressure-tight packaging for shipping via air
transport. The sensor can lose its measuring sensitivity.
► Only transport the sensor via air transport in the appropriate packaging.
11
Storage
The storage temperature may be between 0 °C and +40 °C. Note the maximum
storage period as detailed on the packaging label.
