BX-302-9800 Manual Rev H.doc Overview: This document describes the procedure for using the BX-302 Zero Filter Calibration Kit to audit or adjust the background (BKGD) value on Beta Attenuation Monitors (BAM) particulate monitors. These instructions must be followed carefully to obtain the best accuracy from the unit. BX-302 Zero Filter Variations BX-302 with Cover (81418) About the BAM Background: The Background (BKGD) value is the zero correction (slope offset) used for all Met One Instruments BAM instruments (e.g. BAM 1020, BAM 1022, E-BAM Plus, and E-BAM). The BKGD value is factory calibrated for each BAM instrument under laboratory conditions. Units should have this value verified and/or adjusted by the user during initial field deployment of the instrument, using the BX-302 zero filter kit. The BKGD value should also be audited either seasonally or at least annually afterward. This field zero test corrects the BKGD value to compensate for minor variations caused by local conditions such as inlet heater operation, grounding, and RFI/EMI. It is not uncommon for the initial field zero test to result in a BKGD value that varies from the factory-set value by up to several micrograms. If possible, the zero test should NOT be performed during a period of rapidly changing barometric pressure or ambient/shelter temperature, because rapid changes in air density can be measured as mass noise and may adversely affect the test results. NOTE: The included BX-302 cover should always be installed during Background testing to protect against water intrusion and to prevent sunlight from creating false beta counts. Reference the specific BAM instrument's operation manual for detailed Background test procedures. BX-302-9800 Manual Rev H.doc Page 2
