10-2.5 correlation. The coarse system is based on a pair of the latest revision BAM-1020 beta gauge particulate monitors which have been modified to operate in a Master/Slave configuration. One instrument measures, stores, and displays PM levels as if it were a stand-alone unit.

The BX-COARSE sampling kit includes the BX-965 Report Processor back panel option on both BAM units. It contains all of the same connections as the normal BAM-1020, with the addition of new connections for special data retrieval options. See Sections 8.3 and 10.2 of the BAM-1020 manual for descriptions of the standard terminal connections.

1. Configure your shelter or weatherproof enclosure for the two BAMs as described in the BAM-1020 manual. The inlet tubes of the two BAM-1020 units should be spaced one meter apart when possible. The optional Met One BX-906 dual-unit mini shelter is available if needed, and only requires two short inlet tubes (part 8112-2.25) for setup.

4. Connect the 400658 serial network cable between the “COM 3” ports on the back panel of the two BAM-1020 units. This is the same kind of female-female null serial cable that is supplied with each BAM for serial data retrieval. If it is too short, it can be extended with a normal 9-pin serial cable.

Most of the user interface screens and menus are the same as the normal PM FEM series of firmware, and are described in detail in the BAM-1020 manual. Only the new and different menu items and test functions unique to the coarse system are described below.
