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 E-BAM 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 which should be consulted as needed. Electronic versions of

this manual are also available.

1.2 Technical Service

This manual is structured by customer feedback to provide the required information for setup,

operation, testing, maintaining, and troubleshooting of the E-BAM unit. Should support still be

required after consulting the printed documentation, contact one of the expert Met One Instruments,

Inc. 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 the Met One Instruments, Inc. website. Please contact the service department and

obtain a Return Authorization (RA) number before sending any equipment back to the factory. This

allows for tracking and scheduling service work and to expedite customer service. Please have the

instrument serial number available when contacting the manufacturer.

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.

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.
