All BC 1054 monitors have two product labels with the serial number printed on them. The
labels are located on the upper right corner of the back panel and inside on the backside
of the door by the display. The calibration certicate also has the serial number printed
on it. The serial number is needed when contacting the Met One technical service
department to request information about repairs or updates for a specic monitor.

1.3 About the BC 1054 – Ten Wavelength Black Carbon Monitor
The Met One Instruments, Inc. model BC 1054 MultiSpectrum Carbon Monitor is a ten-
wavelength black carbon monitor, which automatically measures and records optical
transmission across lter media onto which particulate matter has been deposited at ten
wavelengths ranging from 370 nm to 950 nm. From this information the concentration of
black carbon “BC” and particulate matter absorbing in the near-ultraviolet regions may
be determined.
Figure 1-1 The BC 1054 Front Panel
In addition to these two industry-standard measurements, the BC 1054 includes eight
additional wavelength measurements. The additional wavelength channels allow analysis
of carbon particulate at other wavelengths, as Detailed in table 1-1, below.
Table 1-1 BC 1054 BC Measurement Labeling
Measurement Wavelength BC 1054 Label Measurement Wavelength BC 1054 Label
370 nm BC1 590 nm BC6
430 nm BC2 660 nm BC7
470 nm BC3 700 nm BC8
525 nm BC4 880 nm BC9
565 nm BC5 950 nm BC10
Ambient air is drawn into the instrument at a controlled flow rate, generally through a
size-selective PM2.5 or PM1fractionator. The sampled air is subsequently drawn through a
heated inlet and then through special glass ber lter tape, trapping ambient particulate
matter. Optical transmission at each of the wavelengths shown in Table 1-1 is measured
through the lter tape, thereby allowing BC mass concentrations to be calculated at

Page 10 BC 1054-9805 REV A
each wavelength. The lter tape is set to advance automatically when a sucient
amount of particulate matter has been deposited on the tape to cause the attenuation of
channel one to exceed the factory-determined load level. These settings can be
changed, but it is recommended to keep the factory settings unless local requirements
state otherwise.
1.4 Safety Warnings
Optical Warnings: The BC 1054 monitor employs LED light sources ranging from the near
UV (370 nm) to the near IR (950 nm). Some of them emit light that is outside the range of
normal human vision, and thus could present a potential invisible ocular exposure hazard.
The UV light source is a 20 mW LED, emitting at 370 nm. The infrared sources are a 40
mW near-IR LED emitting at 880 nm and a 55 mW near-IR LED emitting at 950 nm.
Appropriate precautions should be taken.
A protective housing with this warning symbol fully encapsulates the light
sources and optics system during normal operation. Whenever the optical
module is disassembled for cleaning, the main power switch must be turned
o and the power cord disconnected to prevent accidental exposure to UV and IR
radiation.
Electrical Warnings: The BC 1054 is a 12 Volt DC powered system. There are no
hazardous live voltages located anywhere inside the instrument. It is equipped with an
external desktop power supply module with a 100-240 VAC 50/60Hz input range, and a
12 VDC, 8.5 A output. The external AC pump box (115 VAC or 230 VAC model) contains
hazardous voltage.
Always disconnect pump box power before opening the pump box to conduct
maintenance.
Neither the BC 1054 instrument, external pump assembly, nor the power supply module,
are weatherproof and should ever be exposed to precipitation or wet conditions.
Thermal Warnings: The instrument contains a 12 Volt 40-Watt internal heater, in the
form of two large, gold colored power resistors and a circulation fan located inside the
electronics chassis. These resistors are usually hot and should not be touched while the
instrument is powered on, or within several minutes after it is powered o.

The BC 1054 must be installed in a clean, dry, weatherproof location such as a walk-in
shelter, a trailer or mobile lab, a mini outdoor shelter, or in a permanent structure.
Instrument Temperature: BC 1054 must be operated at temperatures between 0°C and
40°C.
Rack Mounting: The BC 1054 may be installed in a standard 19” equipment rack and
would require six rack-units of space (6U) if done so.
Benchtop Mounting: The BC 1054 may also be installed on a tabletop. Make sure the
mounting surface is level and that the instrument is secured so that it won’t “walk” due to
vibration. Always leave adequate clearance at the back of the unit for access to the data
ports, power switch, and sampling line.
2.3 BC 1054 Assembly
The following sections describes setting up the BC 1054 and its various sample inlet
congurations. See section 2.3.2 for Dilution Flow setup. Set up the BC 1054 hardware
items and accessories as described below:
2.3.1 Sample Inlet Congurations
The BC 1054 is designed to operate with an in-line PM2.5 or PM1fractionator through
flexible tubing connected to the back of the instrument or within the dilution flow system.
The fractionators (sharp-cut cyclones or SCC) are designed to sample at 2 or 5 LPM.
There are no special installation requirements for the BC 1054 other than the monitor be
no more than 20 feet away from the source of ambient air being sampled and that the
source be directly accessible.
At the sample location, the SCC is coupled directly to the bottom of the 9441 TSP inlet in
stock conguration. It is then mounted on the 8936-5 support tube. The flexible ESD
sample tubing is then slipped over the barbs on the support tube. A worm-gear hose
clamp (pn: 480773) is used to secure the tubing to the support tube. The other end of the
sample tubing is routed to the BC 1054, grounded to a terminal on the back of the
instrument, and is then installed on the rear of the monitor using a push-to-connect
tting (pn: 580399). See Figure 2-1.
NOTE: The factory conguration varies from the dilution flow system conguration.
(Section 2.3.2).

Page 16 BC 1054-9805 REV A
2.3.1.1 Stock Inlet Assembly Installation
1. Connect the SCC to the TSP Inlet: Install PM2.5 or PM1SCC onto the bottom of the
TSP inlet located in the sample area.
2. Mount the SCC to the Support Tube. Once the TSP and SCC are coupled, the
assembly should be mounted on top of the support tube.
3. Route the Flexible ESD Tubing: Flexible tubing (pn: 960216) should be routed from
the base of the support tube in the sample location to the back of the BC 1054. It
should not be connected to the inlet tting at this time. See section 2.3.1.
4. Ground and Install the Flexible ESD Tubing: Place the inlet tubing grounding
assembly (see Figure 2-2) over the BC 1054 end of the sample tubing. Position the
clamp between one and two inches from the end of the tubing (see Figure 2-3) and
tighten it until the clamp grips rmly.
CAUTION: Do not overtighten the clamp and crush the tubing.
Insert the tubing into the ½” Push-to-Connect adapter (pn 580399) and connect to the
Sample Inlet (marked “Inlet” on the back of the BC 1054). Connect the green wire to the
right-most terminal marked Shield on TB-1 on the back of the BC 1054 (see Figure 2-4).

2.3.2 Dilution Flow System Option
NOTE: This section can be skipped if a dilution flow system will not be in use.
The following section describes setting up the BC 1054 with the Dilution Flow System. Set
up the BC 1054 dilution flow system hardware and accessories as described below:
2.3.2.1 Dilution flow system description
In monitoring environments with extremely high concentration levels, the excessive
particulate contained in the sample can result in excessive tape loading. This will result in
frequent tape advances. Rapid depletion of the lter tape and potentially bad data are
the most immediate detrimental side eects. Over time, there will be excessive buildup of
particulate matter inside the instrument, as well. This will result in additional maintenance
being required and greater wear of internal components. To avoid these issues, Met One
Instruments oers the Dilution Flow System.

BC 1054-9805 REV A Page 17
When installed on the back of the BC 1054, a controlled portion of clean air is mixed with
the incoming sample air. Using this feature, the incoming sample concentration levels can
be diluted between 50% and 80%. This means that because the volume of air is carefully
controlled, accurate measurements can be made with a mere 20% of the full particulate
concentration in extreme environments.
2.3.2.2 Dilution Flow System Components
Figure 2-5 Major Components of the Dilution Flow System
2.3.2.3 Dilution Flow Inlet Assembly Installation
1. Connect the Support Tube to the TSP Inlet: Install the TSP Inlet on top of the
support tube. The SCC will be mounted directly to the back of the BC 1054 as part
of the Dilution Flow System assembly.
2. Route the Flexible Tubing: Flexible tubing (pn: 960216) should be routed from the
base of the support tube in the sample location and connected to the inlet tting in
Dilution Flow System assembly that will be mounted on the back of the BC 1054.
For now, route the tubing to the back of the BC 1054 and lay it aside.
3. Connect the BX-597A AT/BP/RH Ambient Sensor: The BC 1054 comes with a BX-
597A combination ambient temperature, barometric pressure, and relative
humidity sensor. The sensor must be mounted to be able to monitor the ambient
conditions of the area being sampled (see Figure 2-1).
a. Route the digital sensor cable (pn: 30010-25) from the corresponding
connector on the bottom of the BX-597A sensor to the correct terminals on
the back of the BC 1054, as shown in Table 2-1.
