1.3 BC 1060 – Two Wavelength Black Carbon Monitor
The Met One Instruments, Inc. model BC 1060 Portable Carbon Monitor is a two-wavelength black
carbon monitor. It automatically measures and records optical transmission across filter media onto
which particulate matter has been deposited. Two industry standard wavelengths, 880 nm and 370
nm are used to determine the concentration of black carbon “BC” and “UVPM” (UV light absorbing
PM), respectively.
Figure 1-1 The BC 1060
Ambient air is drawn into the instrument at a controlled flow rate, generally though a size-selective
PM
2.5
or PM
1
fractionator. The sampled air is subsequently drawn through a heated inlet section
and then through special glass fiber filter tape, capturing ambient particulate matter. Optical
transmission at both wavelengths is measured through the filter tape allowing BC mass
concentrations to be calculated at each wavelength. The filter tape will advance when sufficient
particulate matter has been deposited on the tape to cause the attenuation of the selected channel
to exceed a factory recommended level or a user-selected value.
1.4 Safety Warnings
Optical Warnings: The BC 1060 monitor employs an LED light source in the near UV (370 nm)
and one the near IR (880 nm). This light is outside the range of normal human vision and could
present a potential invisible ocular exposure hazard. The UV light source is a 15 mW LED, emitting
at 370 nm. The near infrared source is a 7 mW IR LED emitting at 880 nm. Appropriate
precautions should be employed.
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 service, the power cord must be disconnected in
order to prevent accidental exposure to UV and IR radiation.

BC 1060-9800 REV B Page 7
Electrical Warnings: The BC 1060 is a 12 Volt DC powered system, and 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 50/60 Hz input range, and a 12 VDC, 8.5 A output. The BC
1060 instrument is housed in a weather-proof case for deployment outdoors.
NOTE: Use ONLY Factory Power Supply. NO SUBSTITUTIONS!
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 being powered off. The inlet heater tube located near the top and
inside the instrument may also be warm to the touch while operating and for several minutes after
powering off.

BC 1060-9800 REV B Page 9
3.2 Electrical Service
The BC 1060 uses an external DC power supply which can be supplied with 100 - 240 VAC, 50 or
60 Hz input power. The sampler is rated at 70 Watts maximum continuous power with the sample
pump running. There are no hazardous live voltages located anywhere inside the instrument. The
power supply provides a 12 VDC, 8.5 A output. It is not weatherproof if removed from its protective
housing so the power supply should never be deployed outdoors without its case.
NOTE: Use ONLY Factory Power Supply. NO SUBSTITUTIONS!
The sample site needs to be equipped with AC power and a standard weatherproof outdoor
electrical outlet.
For critical applications, where possible sample invalidations due to power failures are
unacceptable, the sampler should be equipped with an uninterruptable power supply (UPS). The
supply must be rated for the electrical load and must be appropriately configured for an outdoor
application. Consult a qualified electrical contractor.
3.3 Shelter & Mounting Options
The BC 1060 is a weatherproof monitor designed to be mounted on a stand and then deployed in
the outdoors without the need for a shelter or other housing. However, if it is desired, it may also
be installed in an indoor location such as a walk-in shelter, a trailer or mobile lab, a mini outdoor
shelter, or inside of a permanent structure.
Benchtop Mounting: The BC 1060 may be installed on a table-top. 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 port, power, ambient probe
connections and sampling lines.
3.4 Sample Inlet Configurations
The BC 1060 is designed to operate with an in-line PM
2.5
or PM
1
fractionator through flexible tubing
connected to the back of the instrument. The fractionators (sharp cut cyclones or SCC) are
designed to sample at 2 LPM.
The TSP inlet mounts atop the dilution adapter. The adapter is coupled directly to the inlet of the
SCC which is mounted on top of the 82977 support tube. The flexible sample tubing connects
onto the bottom of the support tube and is routed to the BC 1060 sample inlet on the rear of the
monitor. It connects using a push-to-connect fitting. See Figure 3-2.
3.5 Assembling the BC 1060
The BC 1060 is designed for easy setup and deployment. This allows it to be used for either
permanent long-term sampling at a fixed site or for portable audit sampling for temporary
applications.

Page 10 BC 1060-9800 REV B
Figure 3-1 The BC 1060 Shown with Optional BCX-901 Stand
The following describes the standard method of setting up the BC 1060. If using the optional
mounting stand or sample inlet extension kit, refer to the associated manuals for those items for
additional instructions. Refer to Figure 3-2 and Figure 3-3.
1. Connect the TSP Inlet to the dilution adapter: Slide the TSP inlet onto the top of the
dilution adapter. Be certain the TSP inlet is fully seated onto the dilution adapter.
2. Connect the dilution adapter to the SCC: Slide the dilution adapter onto the inlet of the
SCC. Be certain the dilution adapter is fully seated onto the SCC.
3. Mount the SCC to the Support Tube. The support tube inlet should be inserted into the
outlet of the sharp cut cyclone. Be certain the inlet tube is fully seated within the cyclone.
4. Mount the Inlet Support Tube: Locate the inlet support tube mount on the back of the BC
1060 housing. Lightly pinch the upper and lower grips together and slide the tube through
both mounting holes. At the desired height, release the grips and the tube should be held
securely in place.

BC 1060-9800 REV B Page 11
5. Connect the Tubing: The dilution adapter will have a length of small flexible tubing
installed. This should be routed through the support tube mount to the appropriate fitting on
the back of the BC 1060 and inserted into the push-to-connect fitting. The sample inlet
tubing should be installed onto the bottom of the support tube and then into the sample port
on the back of the BC 1060. Both connections are made using push-to-connect fittings.
6. Connect the Ambient Temperature Sensor: The BC 1060 comes with an ambient
temperature sensor. The sensor should be mounted on the rear wall of the BC 1060 using
the two threaded studs located in the upper left corner. Remove the captive retaining
knobs, place the sensor bracket over the mounting studs and screw the knobs back onto
the rear of the monitor. Once mounted, connect the sensor signal cable to the three-pin
connector located beneath the sensor on the rear of the monitor.
7. Connect the Power Supply: Connect the power supply to the four-pin power connector on
the back panel of the BC 1060. The power supply has a universal AC voltage input. The
included US-type modular power cord can be changed to another type if needed.
The BC 1060 monitor is now ready to have power applied and begin the initial configuration
sequence. Plug in the AC power cable and follow the on-screen prompts. See Section 3.8.
Filter tape installation is described in Section 3.7.

3.7 Filter Tape Installation, Loading, and Filter Material Notes
The BC 1060 carbon monitor uses treated glass fiber filter tape rolls, available from Met One
Instruments under part number 460211. It is essential that this tape be used in the BC 1060 in
order to maintain proper instrument calibration and reproducibility. Since the filter tape advance
frequency depends upon filter-loading, the frequency with which the tape needs to be replaced is
variable. A roll of filter tape is expected to last anywhere from 2 to 12 months, depending on the
sampling conditions, tape load level, load channel and dilution settings selected.
Note: The BC 1060 tape transport system runs the filter tape from left to right. Notice that this
places the clean roll on the left side of the monitor. This is the opposite of the configuration used in
the Met One Instruments BAM-series monitors.
Warning: The filter tape is rolled with the checker pattern on the outside of the roll, and the softer
side on the inside. If the new roll is installed backwards on the supply reel, then the backing
material will be on top inside the measurement module, resulting in improper measurement. The
instrument cannot identify this incorrect condition.
3.7.1 Installing Filter Tape on Initial Setup
1. Apply power to turn the instrument ON.
2. Select SETUP when prompted (see Figure 3-8).
3. Advance past the first two setup screens (see Section 3.8.1).

6. Select YES to reset the tape counter to 100% TAPE REMAINING and advance to the LOAD
TAPE screen (see Figure 3-4).
7. Select OPEN to open the measurement module, if not already open.
8. Loosen the two tape reel knobs and remove the reel covers.
9. Install the new filter tape roll onto the left (supply) reel, with the tape coming off the left side
of the roll. Route the tape exactly as shown in Figure 3-5. It should go under the metal idler,
through the slot in the measurement module, under the encoder wheel, and then up to the
take-up reel on the right side of the instrument. Fasten the loose end of the tape to the left
edge of an empty core tube installed on the take-up reel, with cellophane tape. Make sure
that the softer side is UP and the textured side is DOWN.
10.Align the filter tape and take up the slack by turning the left (supply) reel.
11.Press the MOVE softkey. Verify that the tape spools correctly. Advance at least one turn of
filter tape over the take-up core.

Table 4-2 BC 1060 Menu Hierarchy
Menu selections and instructions are detailed in the following sections of this operating manual as
assigned in the Main Menu column of Table 4-2 above.
Field editing in the BC 1060 is slightly different than the methods used in some of the other similar
Met One Instruments products.
The flashing cursor ■is moved to the field to be changed with the ▼▲ keys. Once the desired field
is highlighted, the ENTER key must be pressed to open it for editing.
A ▼symbol will appear next to opened fields where a pick list is available and the ▼▲ arrow keys
can then be used to cycle through the available choices. Once the preferred option is highlighted,
press the ENTER key again to select it and lock the field. To return to the previous menu, press
ESC.
If a numeric field is opened for editing, the cursor will be positioned at the leftmost digit. Use the
◄► keys to move the cursor to the digit to be modified and then use the ▼▲keys to
increment/decrement the value. Once all of the digits have been set to the required value, press
the ENTER key again to lock the field. To return to the previous menu, press ESC.

Page 20 BC 1060-9800 REV B
Use the ESC key to cancel any edit that may be in progress. The ESC and MENU keys are used
to exit the current menu and return to the previous menu level. If the Main Menu is currently
selected, the monitor will exit to the Main Sampling Screen.
4.4 Start or Stop Sample
This screen is used to begin or end the BC 1060 sampling
operations. It will be labeled on the main menu as either
START SAMPLE or STOP SAMPLE. The label indicates
the action that can be taken when entering this screen.
Once selected, press the START or STOP softkey (shown in
the START mode in Figure 4-3) to begin or end sampling.
See Section 3.8 for more details.
Figure 4-3 The Start Sample Screen
4.5 Load Tape
This screen enables operation of the Measurement Module
assembly and tape spools. Use the OPEN softkey to lower
the bottom of the measurement module and open the tape
path. When opened, the OPEN softkey will read as CLOSE,
indicating that when pressed, the key will close the
measurement module assembly. Use the MOVE button to
advance the tape one sample space. If the measurement
module is closed when the MOVE key is pressed, the BC
1060 will automatically open it and then advance the tape.
Provides the ability to reset the filter tape remaining counter.
REMAINING is the estimated percentage of filter tape
remaining on the current roll. See Section 3.7 for
instructions on loading the filter tape.

4.6 View Alarm Log
This screen is used to view time-stamped alarm events with
the most recent alarm displayed first. To view earlier alarms,
use the arrow keys to navigate through the list. The ◄and
▲keys will scroll to the previous alarm in the list (earlier
time stamps) and the ►and ▼keys will scroll to the next
alarm (later time stamps). This information is also reported
in the Alarm File (see Section 7.3).
