1 INTRODUCTION
1.1 About This Manual
This document is organized with the most important information toward the front of the manual,
such as site selection, installation, setups, and field calibrations, which all BAM 1022 owners
and operators should read and understand. Toward the back are sections that provide in-depth
information on subjects such as theory, diagnostics, accessories, and alternate settings. These
sections provide valuable information that should be consulted as needed. Electronic versions of
this manual are also available. Operators of the monitoring system are encouraged to study this
manual to ensure correct performance, safe operation, and to prevent equipment damage.

1.2 Technical Service
This manual is structured by customer feedback to provide the required information for setup,
operation, testing, maintaining, and troubleshooting your BAM 1022 mass monitor. Should you
still require support after consulting your printed documentation, we encourage you to contact
one of our expert Technical Service representatives during normal business hours of 7:00 a.m.
to 4:00 p.m. Pacific Standard Time, Monday through Friday. In addition, technical information
and service bulletins are often posted on our website. Please contact us and obtain a Return
Authorization (RA) number before sending any equipment back to the factory. This allows us to
track and schedule service work and to expedite customer service. Please have your instrument
serial number available when contacting the manufacturer.

1.3 BAM: Beta Attenuation Monitor
The Met One Instruments Model BAM 1022 Continuous PM Monitoring System utilizes the
principal of beta ray attenuation to accurately measure and report the concentration of airborne
particulate matter (PM) in ambient air. The centerpiece of the measurement system consists of
a beta source that emits a consistent supply of electrons, and a sensitive detector that counts
the incident electrons.
A vacuum pump draws air through a size selective inlet, down the inlet tube, and deposits the
airborne particulate on a filter tape that is located between the beta source and detector. The
accumulation of mass onto the filter tape increasingly attenuates beta ray transmission through
the media.
Beta attenuation through the filter tape is continuously monitored throughout the measurement
cycle. The degree of beta ray attenuation is used to determine the mass of particulate matter
deposited on the filter tape. During sampling, the flow rate is precisely controlled.
Having determined both mass and sample volume, the BAM 1022 calculates and reports the
ambient PM concentration, expressed as µg/m3or mg/m3.
A detailed description of the measurement is provided in Section 8 of this Operating Manual.
BAM 1022 Measurement System
NOTE: For proper performance, the BAM 1022 must be operated outdoors and should not
be installed inside of a building, trailer, or other shelter. It must be allowed to run at
ambient conditions. This is required for the BAM 1022 to operate as a U.S. EPA PM2.5 Class
III Equivalent Method monitor.

1.4 Safety Statements
1.4.1 Beta Radiation
The Met One Instruments BAM 1022 contains a small 14C (Carbon 14) beta radiation-emitting
source. The nominal activity of the source is 60 μCi ±15μCi (microcurries), which is below the
“Exempt Concentration Limit” as defined in USC 10 CFR Section 30.71 –Schedule B. The
owner of the BAM 1022 is not required to obtain any license in the United States to own or
operate the mass monitor. The owner of a BAM 1022 may elect to return the entire mass
monitor to Met One Instruments for recycling of the 14C source when the mass monitor has
reached the end of its service life, although the owner is under no obligation to do so. Under no
circumstances should anyone but factory technicians attempt to remove or access the beta
source. The beta source has a half-life of about 5,730 years, and should never need to be
replaced unless it becomes damaged or corroded. Neither the 14C source nor the beta ray
detector are serviceable in the field. Should these components require repair or replacement,
the BAM 1022 must be returned to the factory for service and recalibration. The BAM 1022 is
manufactured in compliance with the U.S. NRC safety criteria in 10 CFR 32.27.
1.4.2 Other Safety Items
If the BAM 1022 is operated in a manner not specified by the manufacturer, the performance
and protection provided by the equipment may be impaired.
Any repairs or adjustments made to the BAM 1022 that are not outlined within this
document must be carried out only by factory-trained personnel. Under no circumstances
should repairs be attempted by personnel not qualified to service electronic
instrumentation.
Disconnect power to the BAM 1022 power before working on electrical components.
Failure to do so may result in an electrical hazard and could damage the equipment.
Grounding and antistatic procedures must be followed when handling any internal
components. Internal circuitry of the BAM 1022 may be damaged by static electricity.
Do not operate the BAM 1022 in potentially explosive environments.
If safe operation of the BAM 1022 has been impaired, the instrument must be
disconnected from power and secured against unintended operation.
The BAM 1022 should be secured against accidental tipping. Anchoring holes are
provided in the feet at the base of pump box assembly for this purpose.
For procedures not outlined within this document, consult your local Met One Instruments
technical service representative or contact the manufacturer.
