Maintenance
Due to component wear and tear, during extended breaks between
measurements it is better to turn off the sensor unit instead of putting it into
standby mode. For this reason, standby mode should only be used when a
reduced time to operational readiness is required.

Maintenance intervals

Test
Inspection and maintenance by
experts.
Experts are specifically trained employees that have knowledge of and
experience in inspecting and maintaining the relevant devices.
National and international regulations for inspection and maintenance must be
observed.
5.2

Running a functional test

NOTICE
Only perform a functional test using one of the test gases given in the technical
manual.
NOTICE
Never apply test gas with overpressure, instead use a T-piece or the 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 stabilisation have been completed.
Interval
Every 12 months

control valve and
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 to 12 ppm.
If the functional test is not successful:
● Calibrate the sensor unit.
For further information, see the technical manual.
5.3

Carrying out a calibration

Measuring device errors may mean that calibration is not possible.
The Seeker and Analysis measuring modes are calibrated simultaneously. The
calibration process includes a fresh air calibration of the Seeker mode.
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 given in the technical
manual.
NOTICE
Never apply test gas with overpressure, instead use a T-piece or the 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
