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 particles. These beta particles 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 particle signal. The
degree of attenuation of the beta particle 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. An in-depth scientific explanation of the theory of operation and the related equations is
included toward the back of the manual. Complete descriptions of the measurement cycles are
found in Section 6.
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.

E-BAM-9800 Operation Manual Rev M Page 5
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 Ci ±15Ci (microcurries), 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.
1.5 The E-BAM and U.S. EPA Equivalent Methods
The Met One Instruments, Inc. Model E-BAM is not currently designated as a U.S. EPA Federal
Equivalent Method (FEM) for continuous PM10 or PM2.5 monitoring. However, the unit is designed to
accurately predict FRM or FEM concentration measurements when operated in accordance with
this manual. The E-BAM is intended as a rapid-deployment particulate monitor which can be used
for emergency response situations, micro to neighborhood scale particulate studies, perimeter
monitoring, remote monitoring, and other applications where a small, self-contained, portable unit is
required. To that end, the E-BAM is unparalleled in its flexibility and ease of use.
The internal DC pump E-BAM configuration is not usually intended for permanent, long-term
installations at a fixed monitoring site, due to the 4000 hour pump rating. This is often an application
for the Met One Instruments Model BAM-1020, which is an EPA designated FEM for both PM10 and
PM2.5 monitoring, and is intended for continuous operation at a fixed site. Many agencies have
networks which contain both types of Met One BAM units in order to meet their diverse sampling
needs. The following table shows some of the features of the E-BAM compared to the BAM-1020:

2 E-BAM UNIT ASSEMBLY AND START-UP
This section describes assembly, start-up, and filter tape installation for the E-BAM unit.
2.1 Assembling the E-BAM
The standard DC version of 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 and stable.
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 body of the tripod. Secure it with
the supplied washers and nut. This prevents the E-BAM from shifting on the tripod.
3. Install the inlet tube and the PM10 and PM2.5 inlets: Loosen the black 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 black fitting and 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 black 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 the picture below. Lubricate the o-rings as necessary.

4. Install the cross-arm and temperature sensor: Connect the 18” cross-arm to the post on
the back of the tripod with the supplied ¾” x ¾” fitting and set screws. The 9250 ambient
temperature sensor snaps onto the cross-arm and plugs into the bottom of the E-BAM.
5. Optional wind sensor: If an optional EX-034 wind speed/direction sensor is supplied, then it
will come with a longer cross-arm tube to use instead of the short one that came with the
temp sensor. Install the wind sensor on one end of the cross-arm, and the temperature
sensor on the other. 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 the bottom of the E-BAM. The sensor will need to be
oriented to the north. Consult the separate manual that comes with the 034 wind sensor.
6. Power Supply: Many E-BAMs are supplied with an EX-121 AC-to-12 VDC power supply as
shown in the photo below. Bolt it to one of the legs of the tripod with the included U-bolts.
Plug the power supply output cable into the DC power input on the bottom of the E-BAM.
When the power supply is plugged into AC power, the E-BAM will turn itself on automatically.
Note: If the E-BAM is to be powered by a battery array or solar system, or if the unit is
supplied with an external AC pump box with a built-in power supply, then these items will
plug into the E-BAM power input instead of the normal power supply.

E-BAM-9800 Operation Manual Rev M Page 9
7. Optional met sensors: If the E-BAM is supplied with other optional met sensors such as
ambient RH or barometric sensors, then these attach to the cross-arm and plug into the
same connector as the temperature sensor, using a supplied splitter junction box.
2.2 Electrical Connections
The standard 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
options. Each connector has a different pin configuration to prevent plugging cables into the wrong
connector. The E-BAM will turn on when a power source is connected to the power input. Note:
There is a 3-color LED located on the bottom of the E-BAM near the electrical connectors. This LED
may flash or hold various colors, but is used for factory test software applications only, and does not
indicate any specific status information to the user.
The E-BAM chassis ground lug should be connected to an earth ground whenever possible, to
reduce electrical noise in the unit.

2.3 Power-up and Automatic Operation
The E-BAM is designed to turn on automatically when power is applied. The unit will ask if you are
ready to start, then prompt you to verify several setup menus which are described below. Then the
unit will perform an automatic self-test routine which takes several minutes. After the self-test, the
unit will begin sampling automatically.
Note: If no keypad 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.
2.4 Power-up Settings Verification and Automatic Self-Test
The E-BAM will prompt you to verify several setup parameters 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 7 for detailed descriptions of the SETUP parameters.
When power is applied to the E-BAM, the unit will show the firmware revision and unit serial number
for a moment, then display the welcome screen:
Press the YES soft key, and the clock screen is displayed as shown below. If the time and date are
correct, press the YES key. If you need to change the time or date, press NO and the display will
show the time/date set screen. Use the arrow keys to change the values, then press SET. Or press
CONTINUE to go on without making changes.
After the time is verified, the unit will display the AVERAGE PERIOD screen shown below. This
menu is important to understand. See Sections 6.2 and 7.2 for detailed descriptions of these
parameters. Press OK if the settings are correct. If the settings need to be changed, press the EDIT
key to enter the edit mode. Select the parameter to be changed with the ◄► keys, and modify the
settings with the ▲▼ keys and press SAVE. Press CONTINUE to exit the edit mode without making
changes.

E-BAM-9800 Operation Manual Rev M Page 12
LOCATION is an ID number which will appear in the data array to indicate which unit collected the
data, and to enable tracking of measurement information. This is used instead of a UNIT ID
because the E-BAM is portable. This may be any number from 01 to 99.
TAPE ADVANCE is how often the E-BAM will automatically advance to a new spot of filter tape.
This value can be set to 1, 2, 3, 4, 6, 8, 12, or 24 hours. The default setting is 24 hours for maximum
tape life. The unit will override this setting and automatically advance the filter tape if the
concentration is too high and the filter tape becomes clogged. If the filter tape is advanced due to
high concentrations, an alarm will be recorded in the alarm log. Note: the tape advance setting does
not change how often the concentration is calculated or stored.
REALTIME AVG is the averaging period for the real-time concentration value. The real-time
concentration measurement is updated every minute, and the REALTIME AVG is the mean of these
real-time values over the selected time period. The REALTIME AVG may be set to the following
time periods: 1, 5, 10, 15, 30, or 60 minutes. This also sets the averaging period for the datalogger.
See Sections 6.2 and 7.2 for important considerations regarding this setting.
After the real-time settings are verified, the E-BAM will go on to display the MACHINE TYPE screen.
Press EDIT to change the setting with the arrow keys, or press OK to go on without changes:
MACHINE TYPE tells the E-BAM which type of inlet it is equipped with, PM2.5 or PM10. The only
difference between the two is whether a PM2.5 cyclone is installed or not. The E-BAM will put the
machine type setting onto the data array, so that you can tell if the collected data was PM2.5 or
PM10. The screen refers the user to a picture located inside the door of the E-BAM for easy
identification of the two possible inlet types:

E-BAM-9800 Operation Manual Rev M Page 13
After the MACHINE TYPE is set or verified, the E-BAM will raise the nozzle and check to see if the
stainless steel shipping shim is installed under the nozzle. Note: The shim is attached to the unit
with a tether chain, and is also used for the zero portion of the span membrane test. The shim
should be installed any time the E-BAM is shipped or transported in order to prevent nozzle
damage. The unit can sense the shim with a photo sensor. If the shim is still in place the unit will
display the message “PLEASE REMOVE NOZZLE PACKING MATERIAL”.
After the nozzle shim has been removed, the E-BAM will check if a roll of filter tape installed. If tape
is already installed, the unit will go on to the power status screen. If no tape is detected, the unit will
prompt you to install a new roll:
Install a roll of filter tape as described in Section 2.5. When the filter tape is installed, press
CONTINUE. The unit will again try to detect the tape. If tape is detected, the unit will go on to
display the power status screen. This is mostly useful if the unit is powered with batteries:
Press CONTINUE to proceed. The unit will begin the self-test process and will show “SELF TEST
RUNNING…” on the display. The self-test takes several minutes and can only be bypassed by
pressing the ESC key. The unit will test the nozzle, tape motor, beta detector, pump, flow sensor,
and pressure sensors. If a fault is detected during the self-test, the hardware failure screen will be
shown. Press CONTINUE to view the cause of the failure. See Section 8.1 for error descriptions. In
the example below, the operator has forgotten to connect the 9250 ambient temperature sensor to
the E-BAM. The unit has indicated that the sensor is not operational. If a hardware failure is
detected, the problem must be corrected before proceeding. Press the MENU key to enter the menu
system if needed. Other hardware failures that will hinder E-BAM operation include:
Ambient or filter temperature sensor missing or failed.
Ambient or filter pressure sensor failure.
Broken or missing filter tape.
Low battery voltage or DC input voltage below 10 volts DC.

If the self-test finishes without errors, the screen will display that the unit is functioning properly.
Press CONTINUE to go on to the start operation screen as shown below. Press YES to immediately
start the E-BAM sampling on a normal operating cycle. Press MENU to forgo operation and enter
the main E-BAM menu system instead.
This is the end of the automatic E-BAM start-up sequence. It is recommended that you perform a
leak check and flow check/calibration as described in Section 5. Become comfortable with these
checks, as they will be performed often.
2.5 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 and ambient particulate
levels. It is important to have several spare rolls of tape available to avoid data interruptions. Some
agencies save used rolls of tape for post-sampling analysis, although there is no guarantee that the
sampled spots have not been contaminated. Used filter tape should never be “flipped over” or re-
used! This will result in measurement problems. Loading a roll of filter tape is a simple matter using
the following steps:
1. If the sample nozzle is in the down position, it will need to be raised. Enter the LOAD TAPE
screen in the main E-BAM menu. The unit will raise the nozzle and prompt you to load the
tape.
2. If you are replacing a used roll of tape. Remove the old roll, then thoroughly clean the nozzle
and vane as described in Section 5.1.
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, you can use the empty cardboard core tube left over from your 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 below. 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.

2.6 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. Some agencies choose to discard the first few hours of concentration data
after the E-BAM unit is powered up.

3 E-BAM USER INTERFACE and MENU SYSTEM
This section describes the E-BAM user interface system, and describes the functions of the main
menu options, including how to view data and errors.
3.1 The User Interface - Keypad and Display Functions
The E-BAM user interface consists of a 4x20 character vacuum fluorescent display (VFD) and a
dynamic keypad. The two white keys under the display are called “soft keys”. These are dynamic
keys which change in response to a menu option displayed directly above the key on the bottom
row of the display. The function of these keys depends on which menu is shown on the display, and
are often used for functions such as “save”, “edit”, and “set”.
The four red arrow (cursor) keys are used to scroll up, down, left, and right, to navigate in the menu
system, and to select items or change fields on the screen. The arrow keys are also often used to
change parameters or increment/decrement values in the menu system. The right arrow key can be
used to wake up the display if it has turned off to save power.
The MENU/SELECT key is used to enter the main menu or to select an item in a list. The ESC key
is used to escape or exit out of a menu.

3.2 Using the Main Sampling Screen
The E-BAM display shows the Sampling screen when the unit is in normal operation. The active
display area shows the current date and time, the latest real-time average concentration, and the
last hourly concentration. Also shown is a status message, such as “SAMPLING…”. To view the
rest of the instantaneous sensor parameters which do not all fit on the display at once, press the
down ▼ arrow. The date and time will remain at the top of the display at all times.
To view past data, use the left ◄ arrow key to scroll back to previous data records. There will be
one complete data record for every real-time average interval, indicated by the time/data stamp at
the top of the screen. For example, if the real-time average is set to 10 minutes, then there will be a
complete data record stored every 10 minutes as shown below. Again, you can use the ▼ key to
view the rest of the sensor parameters for that record. Press the ESC key at any time to return to
the current concentration sampling screen.
Main Sampling Screen Format
Below is a table which describes the other parameters visible in the main sampling display as
shown above. In addition to the hourly and real-time average concentrations, these are all of the
logged parameters in the E-BAM:

3.3 Using Main E-BAM Menu System
The main E-BAM menu system can be entered at almost any time by pressing the MENU/SELECT
key. Use the ▲▼ arrow keys to select the desired menu option, then press the MENU/SELECT key
to enter the selected sub-menu. The functions in the FIELD CALIBRATION menu are described in
Section 5. The functions in the SETUP menu are described in Section 7. All of the other main menu
functions are described below.
The Main E-BAM menu
OPERATE:This menu option starts the E-BAM into normal operation mode and starts a new
sample cycle. You will see a message which says” WARNING: START OPERATION?” Press the
YES key to start a new sample. If the unit is already sampling, this option will simply exit the main
menu and display the main sampling screen.
LOAD TAPE:This menu option is used for filter tape installation. If this option is selected, the E-
BAM will simply raise the sample nozzle for easy tape loading, then display “PLEASE LOAD TAPE.”
Load the tape and press the CONTINUE key to go back to the main menu.
SETUP:This is the setup menu for the E-BAM. All of the setup parameters in this menu are
described in Section 7.
MEMORY:This menu option displays the amount of memory left in the E-BAM digital data system
as shown below. To erase the memory, press the CLEAR key. Use the arrow keys to select either
the DATA LOGGER or ALARM LOG to be cleared, then press the CLEAR key again. The unit will
show a CAUTION screen. If you are sure you want to erase the selected log, press the YES key.
CAUTION! Once the data log or the error log is cleared, the erased data can never be
recovered.
The unit contains memory for 4369 data records. The memory will fill up faster the shorter the real-
time average interval is set to, as shown in the table below. This is another reason why the 1 and 5

SELF TEST: This menu option starts the E-BAM on an automatic self-test cycle, just like the self-
test it performs when powered on. Press the ESC key to escape from the self-test and return to the
main menu.
FIELD CALIBRATION:This is the field calibration menu for the E-BAM. All of the calibrations and
tests in this menu are described in Section 5.
SHUTDOWN / SHIPPING:This menu option is used to prepare the E-BAM for transport. When
you enter this screen, the nozzle will raise, and the display will show “PLEASE INSERT NOZZLE
PACKING MATERIAL”. This is the empty zero membrane shim which is connected to the unit with a
tether chain. This shim prevents damage of the nozzle during transport or shipment. Insert the shim
under the nozzle with the tab extending through the slot. The E-BAM will automatically lower the
nozzle onto the shim, then display: “OK TO TURN OFF E-BAM”. The power cord can now be
unplugged to power off the E-BAM. Note: It is OK to power off the E-BAM at almost any time during
normal operation. This menu simply allows the opportunity to insert the nozzle shim.
VIEW ALARM LOG:This menu option allows you to quickly view the error log entries in the E-
BAM without having to download the digital data. The screen will display the type or error, as well as
the time and date when the error occurred. Scroll through the error records using the ◄► arrow
keys. Press the MENU/SELECT key to return to the main menu.
ABOUT:This menu option displays the E-BAM firmware version and revision, as well as the E-
BAM serial number as shown in the example below. The up/down arrow keys may be pressed to
change which firmware version is shown. The E-BAM has two separate firmware files. One is for the
master CPU and the other is for the 3610 I/O control board. Press the MENU/SELECT key to return
to the main menu.
