Aethalometer
Model AE33
14. Observe the flow measured by your flow meter.
IMPORTANT ! - make sure that your flow readings are reported at the same "Standard"
reporting conditions of Temperature and Pressure that you are using in the Aethalometer.
Many flow meters display flow at "actual" conditions (i.e. local T and P); and the same result
corrected to "standard" conditions.
15. Press the input box field and enter the flow from the external flow meter.
IMPORTANT ! – units are milliliters per minute (mLPM).
16. Confirm by pressing "OK".
17. The second part of the procedure is to measure the flow once again: but through the
rubber flow calibration pad, rather than the filter tape.
18. When prompted, remove the filter tape and install the rubber flow calibration pad with the
notch facing towards you.
19. When ready, press "OK".
20. Repeat the procedure as before when measuring the flow through the filter tape.
21. When finished, remove the flow calibration pad and replace the filter tape. Press "OK"
when done.
22. The test is now completed.
23. The report shows: Instrument serial number, date and time of the test, and the results of
the test - selected flow and flows through the filter tape and calibration pad.
