9.6 Clean Air test

The Clean Air test is conducted using the built-in filter to determine the stability and
performance of the Aethalometer under the air flow conditions.
To perform the clean air test, select Operation/General/Clean air test. The Clean Air Test
duration is 20 minutes, during which a Status Code of 2048 will be shown. At the end of the
test, a report is generated and saved to the CF card.
1. If the measurements are running, press 'Stop'.
2. Go to the "Operation" / "General" screen, and press the "Clean Air" button in order to start
the test.
3. A new screen appears listing all relevant information about the test settings (test duration,
flow and timebase).
4. When ready, press "OK".
5. The instrument will now start with the test.
6.The Clean Air test uses a built-in filter to determine the stability and performance of the
Aethalometer under dynamical conditions of air flow. Air is drawn through a cartridge filter
(mounted on the top of the optical chamber), and this particle-free air then flows through the
analytical system.
