Introduction
Section 1 - Introduction
OMEGA’s BB-2A Series Blackbody Calibration Source has been
designed for ease of use and reliability whenever you have the need
to test or calibrate non-contact infrared temperature instruments. It is
important that you read this manual completely and follow all safety
precautions before operating this instrument.
1.1 General Description:
The Model BB-2A is a portable, rugged, bench-top, blackbody
calibration source. The calibrator is used to test and calibrate infrared
pyrometers. The front 159 mm (6.25”) square plate has a 133 mm
(5 1⁄4”) circular target area with an emissivity of 0.95 and can be set
to any temperature between 66 to 343°C (150 to 650°F). For ease of
reading, a bi-metal thermometer is included. Please note that we do not
recommend this unit to be used as a primary calibration reference.
1.2 Safety Warnings and Precautions:
•F
ollow all safety precautions and operating instructions outlined in
this manual.
•N
ever leave your calibration unattended when in use.
•K
eep out of reach of all children.
•N
ever touch the target plate when hot.
• Never place any object within 3 inches of the plate when hot.
•D
o not operate in flammable or explosive environments.
•N
ever operate with power cord other than the one provided with
your unit.
•R
emove and or disconnect main power cord before attempting any
maintenance or fuse replacement.
•D
o not connect this unit to a non-grounded, non-polarized outlet or
power source.
• T he target plate should not be used as a heating plate for any type
of material or liquid.
• T his unit is intended for indoor use only. Protect from moisture and
rain.

2.1
Unpacking
Remove the packing list and verify that you have received all your
equipment, including the following items:
• BB-2A Blackbody Calibration Source
• Dial Temp. Thermometer, Model H
• Users Manual
If you have any questions about the shipment, please call our Customer
Service Department at
1-800-622-2378 or 203-359-1660. We can also be reached on the
Internet at omega.com
e-mail: cservice@omega.com
When you receive the shipment, inspect the container and equipment
for any signs of damage. Note any evidence of rough handling in transit. Immediately report any damage to the shipping agent.
NOTE
The carrier will not honor any damage claims unless all
shipping material is saved for inspection. After examining
and removing contents, save packing material and carton
in the event reshipment is necessary.
2.2 Mounting and Setup
Place the BB-2A Blackbody Reference on a sturdy surface in a vertical
position and allow space on all sides of the unit for ventilation.
Assemble the Dial Temperature thermometer by inserting the stem of
the thermometer into the large hole in the middle of the top surface
of the target plate. Make sure the rocker switch and the temperature
control knob is on the OFF position. (Rotate the knob counterclockwise
if necessary). Plug in the power cord into a convenient voltage outlet.
The BB-2A is designed to operate within an ambient temperature range
from 10°C to 35°C (50°F to 95°F).

Power Connection
Standard (120 VAC~, 50/60 Hz models)
The BB-2A comes with a standard North American 3-prong AC power
cord. Do not use any other power cord other than the one provided.
This cord provides the proper grounding and has been safety tested by
the proper safety agencies.
International (240 VAC~, 50/60 Hz models)
On 240 VAC~, 50/60 Hz models a European style power cord with the
proper color code and approvals is provided with 3-prong connector.
CAUTION
• L ine voltage variations are not to exceed ±10% of
the rated input voltage.
•E
lectrical connections and wiring should be performed
only by suitably trained personnel.
• T o shut down the unit in an emergency, the power
cord can be disconnected from the AC outlet.

Parts and Features
Section 3 - Parts and Features
The BB-2A Hot plate is a general purpose temperature reference source
intended for laboratory use with an operating temperature range from
66°C to 343°C (150°F to 650°F). The front target plate is heated by a
resistance heater, embedded in the refractory material of the bottom
plate. The plates are made of aluminum to aid in uniform surface temperature distribution. The temperature of the plate is controlled by a
bimetallic thermostat sensor. The case supports the aluminum plates,
and also serves to house the electrical connections and the temperature
control components. See Figure 1 for the overall shape and the general
features of the unit.

Operation
Section 4 - Operation
4.1
Setting Temperature:
Prior to connecting your BB-2A hot plate to your electrical supply,
be sure the rocker and the dial switches are in the OFF position. The
power is turned ON or OFF by means of the rocker switch. Push the
rocker switch to turn the unit ON. The hot plate will start heating up
when the pointer is beyond the OFF mark on the dial plate. Turn dial
clockwise to set desired temperature. Dial mark indicate approximate
surface temperature in °C. The green cycle light will illuminate when
the pointer on the dial passes the OFF mark on the dial plate.
When the temperature for a given dial setting has been reached, the
light will cycle OFF and ON to hold that temperature. If the cycle light
is off, hot plate may still be hot.
To turn OFF hot plate, turn dial switch to the fully counterclockwise
position and push the rocker switch down to off position.
4.2
Measuring Temperature:
The 5 1⁄4” target area of the plate is a near ideal blackbody source. The
emissivity of the plate is 0.95. When calibrating an IR pyrometer, hold
the pyrometer perpendicular to the target plate for optimal performance. The proper distance between the IR pyrometer and the target
plate depends on the field of view of the pyrometer. If the pyrometer is
too far away it will scan unwanted surfaces outside of the perimeter of
the target plate. Holding the pyrometer too close could introduce undesirable heat to the IR detector of the pyrometer.
WARNING
• The BB-2A’s target plate can be set to very high tempera-
tures. Exercise extreme caution when operating the unit. Keep
hands and fingers away from the target plate area. Keep
flammable products such as paper, plastics and clothing far
from the unit.
• The BB-2A is a Class II instrument. It is intended to be operated in a laboratory environment only. Never operate the unit
outside or around children.
• Nothing should come in contact with the target plate.Even
when the unit is off.
• Never unplug the unit while it is on. Let it cool down to
lower temperature before turning it off.

attempting any maintenance or cleaning.
5.2.1 Main Body
Only a damp soft rag with a mild cleaning solution should be used
when cleaning the main body of this unit.
5.2.2 Target Plate
Do not attempt to clean the target plate. The target plate has a special
coating applied and cleaning may change the emissivity and performance of your unit.
