•
The inlet must be equipped with a standard EPA PM
10
inlet head. HORIBA BX-802.
•
The unit is operated for hourly average measurements. The PM
2.5
concentration is calculated (external to the
APDA) as a daily average of the hourly concentration measurements made by the APDA-371.
•
The unit must be equipped with firmware revision 3.2.4 or later.
•
The APDA-371 must be operated in proper accordance with this operation manual, revision F or later. A
supplemental BGI Inc. manual is also supplied with the VSCC™.

beta source configuration. All APDA-371 units manufactured after March 2007 have these features standard.
Older units will have to be factory upgraded and re-calibrated to the latest specifications.
•
The unit must be operated with standard glass fiber filter tape.
•
The COUNT TIME parameter must be set for 8 minutes.
•
The SAMPLE TIME parameter must be set for 42 minutes.
•
The BX-302 zero filter calibration kit is a required accessory. This kit must be used to audit the BKGD
(background) value upon unit deployment and periodically thereafter, as described in the BX-302 manual.
•
The unit may be operated with or without a BX-823 eight foot inlet tube extension and with or without
weatherproof outdoor enclosures BX-902 or BX-903.
