1.3 General Description

The Model BB703 is a portable, rugged, bench-top, hot blackbody calibration
source with a built-in precision PID digital controller. The calibrator is used to
test and calibrate infrared pyrometers. The 28.6mm (1.125") diameter target plate
has an emissivity of .95 and can be set to any temperature between ambient +11
to 400°C (ambient +20 to 752°F).

Section 2 - Installation

2.1 Unpacking

Remove the packing list and verify that you have received all your equipment.
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
www.omega.com
e-mail: [e-mail]

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.

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

Mount the unit on a bench, table top or shelf in a horizontal position and operate
at least ten inches from any air obstructions to the front panel, rear panel, side
or top of the unit. Operate the unit in an ambient environment between the
specified 0 to 40°C (32 to 104°F).

2.3 Ambient Temperature

The target plate of the BB703 can achieve any temperature within the specified
temperature range of ambient +11 to 400°C (ambient +20 to 752°F) when being
operated in ambient temperatures up to 25°C (77°F). When operating the unit

at higher ambient temperatures, the user must not exceed the “Maximum
Allowable Target Plate Temperature” shown along the y-axis in Figure 2.
Failure to adhere to these guidelines may cause a safety switch inside the unit
to open the heater circuit. If the PID light is blinking or continuously on but
there is no increase in target plate temperature, then the thermal safety switch
has tripped. In this case refer to Section 3-3.

decrease in minimum target plate temperature of 6.7°F).

2.4 Power Connection

Standard (115 Vac~, 50/60 Hz models)

The BB703 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 (230 Vac~, 50/60 Hz models)

On 230 Vac~, 50/60Hz models an International style power cord with the proper
color code and approvals is provided with stripped wire ends for connection
to the proper connector used in your country or local area, this connector is not
provided.

Electrical connections and wiring should be performed only by suitably
trained personnel.

Be sure that the line voltage powering your unit does not go above or below 10%
of the rated voltages specified above.

Target Plate:

The 1.125" target plate is a near ideal blackbody source. The emissivity
of the plate is .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.

• The BB703’s target plate can be set to very high temperatures. 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 BB703.

• The BB703 is a Class II instrument. It is intended to be operated in 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 or during “Cool Down.”

P.I.D. Indicator:

When this light is illuminated, the unit is heating up the target plate.

WARNING:

NOTE:

P.I.D. Control
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm used in high
end temperature controllers. The controller causes the process to attain the desired temperature
by turning the process on or off. The process may be a heater or refrigerator. As the process
temperature approaches the setpoint temperature the hot or cold process will be pulsed to reduce
the corrective measures and minimize overshooting. The controller provides a visual representation
of the process status through LED indicators. An indicator may be lit continuously, blink or shut off
entirely to indicate that the process is on, being pulsed, or off, respectively.

Modify Key: Press to view and change setpoint.

Decrease Key: Press in conjunction with Modify Key in order to decrease

In the ON mode, the entire unit is powered up. The fan will only activate when
the target plate is been brought up to a high temperature for a period of about
five minutes.

In the STANDBY mode, the unit is powered down except for the fan and fan
thermostat. If the unit has been operated at high temperature and is then put
into standby mode, the fan will still run until the target plate has cooled down to
room temperature.

If the unit is operated at high temperatures in elevated ambient temperatures,
an overheat condition may occur. In an overheat situation a mechanical reset
switch on the right side panel will pop and open the heater circuit. The controller
will still have power. While the

The layout of the front panel
is shown in Figure 3. The BB703 incorporates a PID digital setpoint controller.
In the default mode the digital display indicates the blackbody target plate
temperature known as (PV) Process Variable. Holding down the modify key
causes the display to show the programmed setpoint known as (SV) Setpoint
Variable. Making changes to the setpoint, units of measure and communication
settings are made by pressing the MODIFY key in conjunction with the
INCREASE or DECREASE key. Holding the MODIFY key and INCREASE/
DECREASE key for an extended period will cause the setpoint temperature to
advance more quickly to a desired value. Three scanning speeds are provided:
slow, medium and fast. The minimum and maximum setpoints are locked at 0
and 400°C (32 and 752°F), respectively. While these max. and min. settings are

changeable (see “Changing the Internal Parameters,” Section 3.5), it is strongly
advised not to adjust these parameters.

The BB703 operates at its optimum performance when left with the factory
parameter settings. The only internal parameter that the operator may need to
change is the

The BB703 heat-up and cool-down characteristics are illustrated in the following
graph. The graph illustrates the approximate time required to make a transition
from one plate temperature to another. First determine the current plate
temperature and go to the corresponding row. Now decide the new target plate
temperature and go to the appropriate column. Note that there are X’s along the
diagonal where original and target temperatures are the same.

4.3 Fuse replacement

CAUTION:

WARNING:

Disconnect all power from source before attempting fuse replacement.

CAUTION:

For continued protection against the risk of fire replace with only the same size,
type and rating fuse indicated here and on the rear panel of your unit.

For model BB703 use 1 ea. 250 Vac~, F2A (Fast-Acting, 2 A)
VDE APPROVED (5mm dia. x 20mm long).

For model BB703-230 Vac use 2 ea. 250 Vac~, F1A (Fast-Acting, 1A)

VDE APPROVED (5mm dia. x 20mm long).

NOTE:

Note that for the BB703-230 Vac both fuses need to be checked if there is a
suspicion that a fuse has been blown. One or both fuses may have been damaged.
