2.2 Mounting

Mount the unit on a bench, table-top, or shelf in a horizontal position and
operate at least 10 inches from any air obstructions to the fan, front panel, rear
panel, bottom, and top of the unit, in an ambient environment between the
specified 0 to 50°C (32 to 122°F).

2.3 Ambient Temperature

The target plate of the BB704 can achieve any temperature within the specified
temperature range when being operated in normal ambient temperature
environments. The maximum specified target plate temperature of 398°C

Process Temperature:

This field displays the current temperature of the target plate.

Setpoint Temperature:

This field displays the desired target plate temperature. Once the target plate
reaches this desired temperature, both displays will read the same value.

Target Plate:

The 4" target 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.

CAUTION:

• The BB704’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 BB704.

• The BB704 is a Class II instrument. It is intended to be operated in a laboratory
environment only. Never operate the unit outdoors 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.”

Operation

NOTE:

PID Control:
Proportional, integral, derivative control (PID) 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 light continuously, blink, or shut off entirely
to indicate that the process is on, being pulsed, or off, respectively.

Parameter/Access Key:

Press to scroll through menu parameters.

Raise Key:

Press to increase the selected parameter or scroll upward in the list of possible
settings.

Lower Key:

Press to decrease the selected parameter or scroll downward in the list of pos­sible settings.

AC Power Mains Input and Fuse Compartment:

The customer connects the power cord to the AC Power Input. As a safety pre­caution, the power cord cannot be connected if the fuse compartment is open.
Refer to Section 5.3 for information on fuse replacement.

Reference Probe Connection:

The reference probe enables the user to monitor the target plate temperature
with an external instrument. The wires are connected to a Class A, 0.00385 RTD
Sensor.

Refer to Section 6 for pinout details.

RS-232 Communications Port:

The female DB-9 port allows the customer to make a 3-wire RS-232 interface
with the BB704. A detailed description of this port is in Section 4.

3.3 Changing the Temperature Setpoint

The layout of the front panel is shown in Figure 2. The BB704 incorporates a PID
digital setpoint controller. The upper display indicates the blackbody target plate
temperature known as (PV) Process Variable, while the lower display indicates
the programmed setpoint known as (SV) Setpoint Variable. Changes to the
setpoint, units of measure and communication settings are made via the

and keys. Holding a key in continuously 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.

3.4 Changing the Controller Parameter Settings

The BB704 operates at optimum performance when left with its factory
parameter settings. The only internal parameters that the operator should need
to change are the engineering units (°F or °C) or the serial communications
parameters. See next page for menu hierarchy with factory default settings
(Fig. 4) and programming procedure (Fig. 5).

Figure 5. Programming Procedure

In the event that the unit has been operated outside of operating range, the controller alarm will
disable the heater and the target plate temperature will not rise. Let the unit cool down completely.
Turn the power off and then back on. If the problem is not corrected, contact the factory.

3.5 Heat-Up/Cool-Down Cycle Times

Approximate cycle times for heat up and cool down are given in the table above.
To find a given transition time from an initial temperature to a second target
temperature, follow this procedure: Look for an initial temperature in the left
column. Next, look for the target temperature along the top row. The intersec­tion of the row and column provides the approximate transition time.

temperature will not rise. Let the unit cool down completely. Press the switch
located on the right side of the unit near the handle hinge until a click is heard. If
this has no effect, refer to the troubleshooting section.

Serial Communications (RS-232)

Section 4 - Serial Communications (RS-232)

This method allows bi-directional data transfer via a three-conductor cable con­sisting of signal ground, receive input, and transmit output. It is recommended

that less than 50 feet of shielded cable be used between the computer and this
instrument. This will assure performance of the BB704 to EN61326 standards,
under the EMC. Note that multiple instruments cannot be tied to the same port

in this configuration. The RS-232 port is optically isolated to eliminate ground
loop problems.

Below is a pinout diagram for the serial port of the BB704 as well as the pinout
for a 9-pin PC serial port. Use a straight DB9 (female) to DB9 (male) connector
cable to connect your computer to the BB704. The cable should be attached only
when the computer and BB704 are off.

Only parameters in the parameter list should be modified or queried via the
serial port. Other parameters should be viewed or queried from the controller
directly. It is highly recommended that baud rate for the controller be modified
on the controller directly. Note that both the BB704 and the computer must be
communicating with the same serial communications parameters to establish a
working communication link.

4

The serial communications feature can be tested using a terminal emulation
package. Note that this controller does not time-out waiting for the next char­acter to be transmitted. Be sure not to use the XON/XOFF or hardware hand­shaking. Lastly, it should be noted that following a complete transmission to the
BB704, a response is sent back. If the message was valid, the changed or queried
parameter is echoed back (following the same format). If the message was not
according to acceptable format or was attempting to force a parameter out of
range, an “ERROR” message is echoed.

5.1 Calibration

This unit has been fine-tuned at the factory and calibrated to give optimum
performance at its full temperature range. It is recommended that the unit be
returned annually for re-calibration.

5.2 Cleaning

Remove all electrical connections and power before attempting any maintenance or cleaning.

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.

5.2.3 Fan

The fan filter should be cleaned at least monthly by washing the filter with warm
water and then blowing dry with air. It can be removed by firmly pulling the
black plastic frame outward. The internal protective grill that is seated against
the fan can be cleaned with a soft bristle brush.

5.3 Fuse Replacement
