1.3 E-BAM: Environmental Beta Attenuation Monitor
The Met One Instruments, Inc. model E-BAM automatically measures and records airborne PM10 or
PM2.5 particulate concentration levels using the principle of beta ray attenuation. This method
provides a simple determination of concentration in units of milligrams of particulate per cubic meter
of air. A small 14C (Carbon 14) element emits a constant source of high-energy electrons known as
beta rays. Beta rays are detected and counted by a sensitive scintillation detector. A vacuum pump
pulls a measured amount of dust-laden air through the filter tape, which is positioned between the
source and the detector thereby causing an attenuation of the beta ray signal. The degree of
attenuation of the beta ray signal is used to determine the mass concentration of particulate matter
on the filter tape and the volumetric concentration of particulate matter in ambient air.
The E-BAM is designed as a simple, compact, and self-contained beta gauge, for portable
applications where rapid deployment and short interval real-time measurements are required. In
addition to the main housing, the monitor includes an external AC pump, a multi-parameter ambient
sensor, and a mounting tripod. See section 2.2 for a listing of standard and optional accessories.

E-BAM-9805 Manual Rev B.docx Page 7
1.4 Beta Radiation Safety Statement
The Met One Instruments E-BAM contains a small 14C (Carbon 14) beta radiation-emitting source.
The nominal activity of the source is 60 microcuries, which is below the “Exempt Concentration
Limit” as defined in 10 CFR Section 30.71 – Schedule B. The owner of an E-BAM is not required to
obtain any license in the United States to own or operate the unit. The owner of an E-BAM may
elect to return the entire unit to Met One Instruments for recycling of the 14C source when the unit
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 5730 years and should never need to be replaced unless it
becomes damaged or corroded. Neither the 14C source nor the beta particle detector are
serviceable in the field. Should these components require repair or replacement, the E-BAM must
be returned to the factory for service and recalibration. The E-BAM is manufactured in compliance
with the U.S. NRC safety criteria in 10 CFR 32.27.

2 E-BAM INSTALLATION AND COMMISSIONING
This section describes assembly, start-up, and filter tape installation for the E-BAM unit.
2.1 Unpacking
Any damage 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. Follow any special unpacking instructions provided by the carrier as all items
are then carefully removed from the containers. Inspect each component thoroughly. It is
recommended to document and photograph all damaged packages and items before, during, and
after unpacking them. Contact Met One Instruments, Inc. (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 E-BAM is shipped with the nozzle shipping device installed under the nozzle which prevents
the moving parts of the vane assembly from being damaged in transit. The device must be replaced
anytime the mass monitor is being transported in order to avoid damaging the vane control
mechanism. Do not ship or transport the E-BAM with filter tape installed.
Please keep all special shipping items (box, foam packing material, etc.) used to ship the E-BAM.
They should be re-used if the monitor is transported (changing site locations, returning to the
factory, etc.). Met One Instruments, Inc. is not responsible for damage to the mass monitor if
shipped in non-original packaging or without the shipping shim in place. Contact Met One
Instruments, Inc. (see section 1.2 of this manual) for replacement packing materials, if necessary.

2.3 Assembling the E-BAM
The E-BAM is designed to be field deployable by an average person in less than 15 minutes under
normal conditions. Refer to the photos and diagrams below while performing the following steps to
assemble the unit:
1. Deploy the tripod: Remove the three stainless steel detent pins from the tripod base by
pulling the rings. Unfold the three tripod legs and reinsert the three pins so that each pin
secures a leg in the open position. Make sure the erected tripod is rigid andstable.
Figure 2-1 Tripod Deployment
2. Install the E-BAM onto the tripod: Lift the E-BAM assembly and slide the slot on the back
of the E-BAM over the tab on the top of the tripod. Insert the supplied ¼- 20 bolt through the
tab on the bottom of the E-BAM and through the hole in the bodyof the tripod (see Figure
2-2). Secure it with the supplied washers and nut. This prevents the E-BAM from shifting on
the tripod.
3. Install the inlet components: Loosen the weatherproof fitting on top of the E-BAM and
insert the short inlet tube into the top of the unit. The tube must go through the fittingand
through two O-rings in the top of the E-BAM. Make sure the tube is fully seated by rotating it
back and forth. Tighten the weatherproof fitting to secure the inlet tube. For PM10 monitoring,
install the BX-802 PM10 inlet directly onto the top of the short inlet tube. If a BX- 807 cyclone
is to be used for PM2.5 monitoring, it must be installed under the PM10 head as shown in
Figure 2-2. Lubricate the O-rings as necessary.
Detent Pins

Figure 2-2 Tripod Mounting of the E-BAM
4. Install 597A Sensor: Connect the 597A sensor to the post on the back of the tripod with the
supplied mounting hardware (user supplied 7/16” wrench required). The 597A sensor should
face away from the E-BAM as shown in Figure 2-3. Verify configuration after power- up as
detailed in section 2.7.1.
Figure 2-3 Mounting the 597A Sensor

E-BAM-9805 Manual Rev B.docx Page 12
5. Optional Wind Sensor: If an optional wind speed/direction sensor (such as the EX2-034B or
EX2-AIO) is purchased a cross-arm tube to use for mounting the wind sensor will be
included. Connect the cross-arm to the post on the back of the tripod with the supplied ¾” x
¾” fitting and set screws and then install the sensor at end of the arm as suggested in Figure
2-4. The wind sensor should be as far from the E-BAM unit as possible, and the wind vane
must be able to rotate fully without hitting anything. Plug the wind sensor into the
corresponding connector on thebottom of the E-BAM. Depending on the type of wind sensor,
it may need to be oriented to the south. Consult the separate manual that comes with the
wind sensor for details. Verify configuration after power-up as detailed in section 2.7.2.
Figure 2-4 Sensor Mounting with an Optional Wind Sensor

E-BAM-9805 Manual Rev B.docx Page 13
2.4 Electrical Connections
The E-BAM has a set of weatherproof connectors on the bottom of the unit. These connectors
provide the connections for the power supply, external sensors, and communications.
The E-BAM chassis ground lug should be connected to an earth ground whenever possible, to
reduce electrical noise in the unit.
Figure 2-5 E-BAM Connectors
2.5 Power-up and Automatic Operation
The E-BAM is designed to turn on automatically when power is applied. It will provide options to
start immediately or enter the setup menus. If START NOW is selected, ensure shipping device is
removed. Choosing setup will present several setup menus for verification. These are described in
section 2.6.
Note: If no user activity is detected for several minutes after power-up, the E-BAM will automatically
begin sampling based on the existing setup options and settings, as long as filter tape is installed,
and no hardware or voltage failures are detected. This makes it possible to fully configure and
calibrate the unit in the lab, then simply deploy it to the field and power it up with no further actions
required.
Always remove the shipping device before allowing the monitor to self-start.

E-BAM-9805 Manual Rev B.docx Page 14
2.6 Power-up Settings Verification and Automatic Self-Test
The E-BAM will present several setup parameters for verification whenever it is powered on. These
setup screens can also be viewed or edited in the SETUP menu under the main E-BAM menu
system. See section 3.6 for detailed descriptions of the SETUP parameters.
When power is applied to the E-BAM, the unit will show the startup splash screen for the
touchscreen display for a moment, then display the welcome screen as shown in Figure 2-6.
Figure 2-6 Welcome Screen
Press the SETUP button and the clock screen is displayed (see Figure 2-7). If the time and date are
correct, press the YES button again. If the date or time need to be changed, press the EDIT button.
See section 3.6.1 for details on changing the date and time.
Figure 2-7 Verifying the Clock
After the time is verified, the unit will display the Settings screen shown in Figure 2-8 below. If the
settings need to be changed, press the green bordered value box to be updated and the associated
edit screen will be displayed.
Figure 2-8 Verifying the Initial Settings
Press OK if the settings are correct, after confirming or setting the Location and Data Average
settings, the E-BAM will need to check whether a roll of filter tape installed. The monitor will then
check the tape installation. If no tape is detected, the unit will prompt for installation of a new roll:

E-BAM-9805 Manual Rev B.docx Page 15
Figure 2-9 Verifying Filter Tape is loaded
Install a roll of filter tape as described in section 2.8. When the filter tape is installed, press MOVE.
The unit will again try to detect the tape. If tape is detected, the unit will proceed to the self-test
screen. Press start to begin a self-test. After a successful self-test, press the X to proceed to
operations.
Figure 2-10 Self-Test Screen

E-BAM-9805 Manual Rev B.docx Page 16
2.7 Configuring External Sensors
The E-BAM must have a 597A sensor connected and properly configured for operation. If the 597A
is not present, the E-BAM will not begin sampling. See section 8.1 for more details about available
wind sensors.
2.7.1 Configuring the 597A Sensor
The E-BAM requires a 597A sensor at address 1 of its serial network to begin sampling. Once the
physical connections are made the sensor is programmed using the Digital Link screen located in
the Test menu (see section 3.5.11).
Upon entering the Digital Link screen, any digital sensor
connected to the E-BAM with address 1 or 2 programmed
in it will appear in either the Sensor 1 or Sensor 2 fields, as
appropriate. In addition to the sensor type, the address
fields on this screen also display the firmware currently
installed in the sensor.
Figure 2-11 shows a typical configuration.
Figure 2-11 The Digital Link Screen
The State field indicates that the E-BAM is either starting up digital communications or waiting for a
response from the sensor. If either the sensor type or firmware revision is missing or incorrect,
communications are not properly established with the sensor. The grey SETUP button in the lower
left corner provides access to the Digital Setup screen for configuring the addresses of the digital
sensors. See section 2.7.2 for details.
2.7.2 Changing Sensor Addresses
The default address for most Met One Instruments, Inc. digital sensors is 1.
If a connected sensor has an address other than 1 or 2, it
can be located in the Digital Setup screen by pressing the
grey SCAN button in the bottom left corner (see Figure
2-12). The E-BAM will scan through all potential network
address nodes to locate any connected devices. Progress
of this scan can be seen in the third address field label
(which displays Addr 3, by default) and the word
“Scanning” will appear in the field itself.
Figure 2-12 Scanning for Sensors
If a device is located at some other address, it can be
changed by pressing the grey CHANGE button next to the
third address field. In the example shown in Figure 2-13,
the 597A has been configured for address 2. Pressing the
grey SET 1 button will update the address in the sensor to
address number 1 and exit back to the main Digital Link
screen. The Sensor 1 field will now display the 597A
details like Figure 2-11.
Figure 2-13 Change the Address
If two sensors share the same address, disconnect one of them and then use the CHANGE button
to set the other one to a different address. Remember that the 597A must be configured for address
number 1 and if an optional wind sensor is connected, it will need to be set to number 2.

E-BAM-9805 Manual Rev B.docx Page 17
2.8 Filter Tape Loading
Filter tape must be loaded into the E-BAM for sampling. One roll of tape will last anywhere from a
few weeks to more than a year, depending on the Tape Advance setting (see section 3.6.5) and
ambient particulate levels. It is important to have spare rolls of tape available to avoid data
interruptions. Used filter tape should never be “flipped over” or re-used. This will result in inaccurate
measurements! When loading a roll of filter tape, use the following steps:
1. If the nozzle is in the down position, it will need to be raised.Enter the Load Filter Tape
screen in the Operate menu. The unit will raise the nozzle and provide a prompt to load the
filtertape.
2. If replacing a used roll of tape, remove the old roll and then thoroughly clean the nozzle and
vane as described in section 5.5.
3. An empty core tube must be installed on the left (take-up) reel hub. This provides a surface
for the used tape to spool-up on. Met One supplies a plastic core tube to use with the first roll
of tape. After that, use the empty cardboard core tube left over from the last roll to spool-up
the new roll. Never fasten the filter tape directly to the aluminum hub!
4. Load the new roll of filter tape onto the right (supply) reel and route the tape through the
nozzle area as shown in Figure 2-14. Attach the loose end of the filter tape to the empty core
tube with tape.
5. Rotate the tape roll to remove excess slack, then install the plastic spool covers tightly. The
spool covers clamp the tape rolls to the hubs to prevent them from slipping.
6. Press the grey MOVE button to verify tape is properly loaded.
7. Press the X button to return to the Operate menu.
Figure 2-14 Proper Loading of the Filter Tape
2.9 Warm-up Period
The E-BAM must warm up for at least one hour before optimum accuracy of the concentration data
can be obtained. This is because the beta detector contains a vacuum tube which must stabilize.
This applies any time the unit is powered up after being off for more than a moment. Setups, tests,
and flow calibrations can be performed during this warm up time. The first hour of data should often
be discarded or ignored.
