Maintenance intervals

Test
Inspections and maintenance must be
carried out by specialists.
Specialists are personnel with specific training, knowledge and experience
inspecting and maintaining the relevant devices.
Observe national and international regulations for inspections and
maintenance.
5.2

Running a functional test

NOTICE
Only perform a functional test using one of the test gases indicated in the
technical manual.
NOTICE
Never apply test gas with overpressure, instead use a T-piece or a gassing
adapter (order no. 6851850) between the test gas cylinder and the sensor unit.
Only use a standard control valve (order no. 6810397) with 0.5 mL min
Requirements:
Suitable test gas cylinder with standard 0.5 mL min
gassing adapter fitted.
The sensor unit is turned on, connected to the mobile app, and the start-up
phase, heat-up phase, and temperature stabilization have been completed.
1. Connect the test gas cylinder to the sensor unit using the gassing adapter.
The water and dust filter must be fitted.
2. Start the functional test in the mobile app.
3. The result should differ from the test gas by a maximum of 20 %. At a test
gas concentration of 10 ppm, for example, the functional test is successful
with a result between 8 and 12 ppm.

If the functional test is not successful:
● Calibrate the sensor unit.

Carrying out a calibration

Measuring device errors may mean that calibration is not possible.
WARNING
Daily calibration may be necessary depending on the conditions of use. To
determine the calibration status by applying test gas, see functional test. If no
deviations in the calibration status are observed in consecutive tests, the
calibration interval can be gradually extended to up to 60 days. Further
information is available from your Dräger representative. If necessary, calibrate
the sensor unit.
NOTICE
Only carry out a calibration using one of the test gases indicated in the technical
manual.
NOTICE
Never apply test gas with overpressure, instead use a T-piece or a gassing
adapter (order no. 6851850) between the test gas cylinder and the sensor unit.
Only use a standard control valve (order no. 6810397) with 0.5 mL min
Requirements:
Suitable test gas cylinder with standard 0.5 mL min
gassing adapter fitted.
The sensor unit is turned on, connected to the mobile app, and the start-up
phase, heat-up phase, and temperature stabilization have been completed.
1. Connect the gas cylinder to the sensor unit using the gassing adapter. The
water and dust filter must be fitted.
2. Start the calibration in the mobile app and follow the instructions. The user is
automatically guided through the calibration process and notified when the
test gas needs to be applied.
