Purpose: Verifies that the airflow used in the calculation of data for the Aethalometer and the Nephalometer represents flow entirely from the inlet.
Required Equipment: Bios with High Cell
Aeth/Neth inlet connection
Reference: SOPMAN
1. Down the AETH and NETH with the set flags function on the site analyzer screen.
2. Equip the BIOS with the “High Cell”, rubber tubing, and AETH/NEPH inlet adapter (1” rubber tubing with connecter to the 3/8” bios tubing).
3. Record temperature with Psychrometer and pressure from site manager (BP).
4. Remove Sharp-cut cyclone from the AETH/NEPH inlet.
5. Connect the Bios tubing from the “Outlet” side of the cell to the AETH/NEPH inlet.
6. Hold down the select and enter buttons on the BIOS for 2-3 seconds and release to begin reading.
7. Record 10 step VAve from Bios three (3) times and average the results.
8. Remove the bios connecter and replace the Sharp-cut cyclone to the inlet.
9.
Enter data into a new QA Result in
SiteManager. The Data Product is
10. Up the AETH and NETH from the Set Flags.
