Page 5: Section 1 - Introduction
BB702 Introduction Section 1 - Introduction Your BB700 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. -
Page 6: General Desrciption
Figure 1. IEC symbols General Description The Model BB702 is a portable, rugged, bench-top, blackbody calibration source with a built-in precision PID digital controller. The calibrator is used to test and calibrate infrared pyrometers. The 2.5 inch Diameter target plate has an emissivity of 0.95 and can be set to any temperature between ambient +11 to... -

5 to 45°C (41 to 113°F). Ambient Temperature The target plate of the BB702 can achieve any temperature within the specified tem- perature range when being operated in ambient temperature up to 32.2°C (90°F). When operating the unit at higher ambient temperatures, the user must not exceed the “Maximum Allowable Target Plate Temperature”... -
Page 8: Power Connection
Power Connection Standard (115 VAC~, 50/60 Hz models) The BB702 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. -
Page 9: Section 3 - Operation
IR detector of the pyrometer. CAUTION: The BB702’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 BB702. -

BB702 Operation 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. -
Page 11: Changing The Temperature Setpoint
BB-702. A detailed description of this port is described in Section 4. Changing the Temperature Setpoint The layout of the front panel is shown in Figure 3. The BB702 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. -
