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.

2 INSTALLATION & COMMISSIONING
2.1 Unpacking
Any damages incurred to the equipment during shipping are the responsibility of the carrier. If
any damage to the shipment is noticed before unpacking, a claim must be filed with the
commercial carrier immediately. You should follow any special unpacking instructions
provided by the carrier as you then carefully remove all items from the containers and inspect
each component. It is recommended to document and photograph all damaged packages and
items before, during, and after unpacking them. Contact Met One Instruments (see section 1.2
of this manual) to arrange for any replacement items needed.
Unpack the mass monitor and accessories and compare them to the packing list to make sure
all items are present.
The BAM 1022 is shipped with a white plastic shim pinched under the nozzle of the mass
monitor which prevents the moving parts of the nozzle assembly from being damaged in transit.
The shim must be replaced anytime the mass monitor is being transported in order to avoid
damaging the nozzle control mechanism. Do not ship or transport the BAM 1022 with filter tape
installed.
Please keep all of the special shipping items (box, foam packing material, etc.) used to ship your
BAM 1022. They should be re-used if you must transport your monitor (changing site locations,
returning to the factory, etc.). Met One is not responsible for damage to the mass monitor if
shipped in non-original packaging, or without the shim in place. Contact Met One Instruments
(see section 1.2 of this manual) for replacement packing materials if necessary.

2.3 BAM 1022 Installation for FEM Monitoring Applications
The BAM 1022 is a weatherproof monitor and must be operated outside of any additional
enclosures in order to maintain its US-EPA Class III designation. Its housing is designed to
maintain a near constant temperature difference between ambient and measurement conditions.
The required constant temperature difference will not be achieved if the BAM 1022 is installed
inside of any structure where the temperature is not allowed to vary with ambient temperature.
There are no special precautions or handling concerns except for the normal level of care
required for handling scientific equipment.
1. Remove the cover from the top of the pump box
assembly and set it aside. Remove all packing
material from inside the box and gather the
loose ends of the cables and tubing.
2. Invert the cover so that the white nipple is
protruding upward, feed the cables and tubing
through it from the bottom, and then replace it
atop the pump box assembly. It should look like
the picture shown here.

BAM 1022-9800 REV E Page 13
3. Open the front door of the main enclosure and remove the protective packing material from
around the touch screen display. On the back of the enclosure, undo the four wing nuts
holding the cable access cover in place and then remove the cover. Set it aside for now.
4. Behind the cable access panel, locate the ingress hole on the right hand side of the bottom
of the enclosure. Lift the monitor and carefully feed the cabling through this hole and
continue to lower it until the white nipple extends in to the housing and the monitor is resting
flat on top of the pump box assembly. Raise the side latches and secure them in place by
tightening the large knob. See pictures below.
CAUTION: Do not lift the BAM 1022 monitor by the angled solar radiation shield mounted to the
top of the enclosure. It is not designed to hold the weight of the full assembly and can easily be
damaged if used to lift the monitor. Instead, firmly grasp the sides of the housing and lift. It
would be easiest to have at least two people for this step.
5. Route the pump cable, the pump box fan cable, and the pump tubing to the appropriate
locations and plug them in to the monitor. Be sure to connect the ground lead tied to the
yellow pump cable to the grounding connection on the BAM 1022 case. Note that the pump
cable connection is a twist lock type. Once inserted, rotate it slightly in a clockwise direction
to lock it in place. To insert the tubing, simply press it in to the fitting. See photos below.

Page 14 BAM 1022-9800 REV E
6. Wrap the lower threads of the pipe seal with Teflon
tape and install it in the top of the enclosure. See
picture to the right.
7. Insert the black sealing ring and loosely attach the
white clamping ring (also shown in the picture at
right) to the pipe seal.
8. Locate the red cap covering the inlet tube receiver
inside the BAM 1022 enclosure. It is found just to the left of the touchscreen display.
Remove the large red cap and a smaller red insert will be revealed beneath it. Remove this
cap as well. See image below left.
9. Slide the inlet tube through the pipe seal on top of the enclosure just until you can see it
inside the enclosure. Position the inlet heater beneath the inlet tube and slide the tube
through the heating element until it just comes in contact with the o-rings. Raise the heater
so it is near (but not touching) the top of the enclosure and fasten it in position with the
supplied hex wrench. See image above center.
10.Rotate the tube so that the heater power cable is facing the back left corner of the enclosure
and route the cable down the large empty hole located near that corner. Push the inlet tube
down all the way and wrap the heater element in the supplied insulating material as shown in
the above right image.
11.Route the inlet tube heater to the power connection labeled
HEATER in the back of the BAM 1022 and plug it in. Note
that this connection is a twist lock type. Once inserted,
rotate it slightly in a clockwise direction to lock it in place.

BAM 1022-9800 REV E Page 15
12.Install the 597 probe on the inlet tube above the roof of the BAM 1022 enclosure using the
U-bolt with the nuts and washers provided. Connect the silver connector of the cable to the
silver connection on the bottom of the sensor. See pictures below.
13.Route the sensor cable to the back of the enclosure and attach it to the connection labeled
as EXTERNAL AMBIENT SENSOR. See photo below left.
14.Install the AC power supply cable to the remaining connection on the bottom of the internal
power strip. It is located next to the ON/OFF switch. See photo above right. Route the
power cable and the sensor cable out of the bottom of the cable access opening.
15.Connect the 9528 grounding cable (included in the accessory kit) to the Ground connection
shown in the above right photo. Route the ground cable out of the bottom of the cable
access opening and connect it to the isolated site grounding rod.

Page 16 BAM 1022-9800 REV E
16.Remove the inlet protector plugs from the BX-802 PM10 inlet head and BX-808 PM2.5 Very
Sharp Cut Cyclone. Install the BX-808 on top of the inlet tube and then the BX-802 directly
above it. See photos below.
17.Plug the AC power cable in to your AC source and turn the power switch to ON. Verify the
fans start up in both the pump box and the main enclosure. The touchscreen display should
also turn on as described in section 4.1.
18.Replace the cable access cover panel on the back of the enclosure and affix it in place with
the four wing nut fasteners. Be sure the flange is on the bottom so that the power cable and
the sensor cable will be pinned between the foam strips and held in place.

BAM 1022-9800 REV E Page 17
2.4 BAM 1022 Power and Electrical Connections
The BAM 1022 should be powered by either a 110 VAC 50/60Hz or 220 VAC 50/60 Hz source.
Before proceeding with electrical connections, review the following notifications:
Ensure that the monitoring site mains power (voltage and frequency) is compatible with
the version of BAM 1022 monitor and accessories that has been purchased. Consult the
