Using This Quick Start Manual
Use this Quick Start Manual with your BB-4A Blackbody Calibrator for easy installation and basic operation. For detailed information, refer to the User’s Guide (Manual # M3264).
PRECAUTIONS:
- Follow all safety precautions and operating instructions outlined in this quick start and accompanying User’s Guide.
- Never leave your calibrator unattended when in use.
- Keep out of reach of all children.
- Remove the cavity wood shipping plug before use.
- Never touch the heater cavity when hot.
- Never place any object within 3 inches of the cavity opening when hot.
- Do not operate in flammable or explosive environments.
- Never operate with a power cord other than the one provided with your unit.
- Remove and or disconnect main power cord before attempting any maintenance or fuse replacement.
- Do not connect and or operate this unit to a non-grounded, non-polarized outlet or power source.
- Do not connect the serial port or reference probe port to equipment with exposed, hazardous, live voltages.
- Protect from moisture and rain.
- The operator of this instrument is advised that if the equipment is used in a manner not specified in this manual, the protection provided by the equipment may be impaired.
General Information
The Model BB4A is a portable, rugged, benchtop, blackbody calibrator source with a built-in precision PID digital controller. The calibrator is used to test and calibrate infrared pyrometers. The heater cavity, with 21.66 mm (0.88″) aperture, has an emissivity of 0.99 and can be set to any temperature between 100 to 982°C (212 to 1800°F).
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 fan, front, rear panel, bottom and top of the unit, in an ambient environment between the specified 0 to 50°C (32 to 122°F).
Your unit was shipped to you with a wood plug installed in the heater cavity to prevent damage during shipping. This plug must be removed before using your calibrator.
Ambient Temperature
The target plate of the BB-4A can achieve any temperature within the specified temperature range when being operated in normal ambient temperature environments. The maximum specified heater cavity temperature of 982°C (1800°F) can be achieved over the entire specified ambient temperature range.
Front Panel
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.
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.
Mode Key:
Press to save settings and exit a menu level.
Back Panel
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 the User’s Guide for information on fuse replacement.
Reference Probe Connection:
The reference probe enables the user to monitor the target plate
temperature with an external instrument. A “K” type thermocouple reference
output is provided.
RS232 Communications Port:
The Female DB-9 port allows the customer to make a 3-wire RS232
interface with the BB-4A
Thermal Reset Switch
In the event that the target plate temperature and/or ambient temperature
exceed the acceptable limit, this reset switch will pop open.
The controller will appear to be demanding a temperature increase but the
target plate temperature will not rise. Let the unit cool down
completely. Locate the hole for the safety switch on the right side of the
unit behind the carry handle. Using a non-conductive thin tube or pin, insert
it into the hole and press in the safety switch until you hear a click. This
will reset the over-temperature protection. If this has no effect, refer to
the troubleshooting section in the user’s manual.
Changing the Temperature Setpoint
The BB-4A’s 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. Making changes to the setpoint, units of measure (°F/°C) and communication settings (BAUD, etc.) 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.
Menu Heat Up/Cool Down Cycle Time Tables
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.

Reference Probe
A thermocouple reference port is provided for monitoring cavity temperature with an external instrument. A standard thermocouple panel jack is provided (OMEGA# RSJ-K-R). If a voltmeter is used to read the output, be sure to use an Icepoint reference call (TRCIIIA) or a cold junction compensator (CJ, MCJ, SMCJ).
RS232 Communication
The RS232 port provides the customer with bi-directional data transfer via a three-conductor cable consisting of signal ground, receive input, and transmit output. It is recommended that less than fifty feet of shielded cable be used between the computer and this instrument. Use a straight DB9 (female) to DB9 (male) connector cable to connect your computer to the BB-4A. The cable should be attached only when the computer and BB-4A are off.
For detailed RS232 communication functionality, refer to the User’s Guide (M3014).
