Page 5: Section 1 Introduction
BB701 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 Description
Figure 1. IEC symbols 1.3 General Description The Model BB701 is a portable, rugged, bench-top, hot/cold blackbody calibration source with a built-in precision PID digital controller. The calibrator is used to test and calibrate infrared pyrometers. The large 2.5 inch Diameter target plate has an emissivity of 0.95 and can be set to any temperature between... -

4.4 to 43°C (40 to 110°F). 2.3 Ambient Temperature The target plate of the BB701 can achieve any temperature within the specified temperature range of -18 to 149°C (+0 to 300°F) when being operated in normal ambient temperature environments. The maximum specified target plate temperature of 149°C (300°F) can be achieved over the entire specified ambient... -
Page 8: Power Connection
2.4 Power Connection Standard (115 VAC~, 50/60 Hz models) The BB701 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 12: Changing The Temperature Setpoint
BB701. 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 BB701 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. -
Page 13: Changing The Controller's Parameter Settings
NOTE: Only the boldface parameters are active for the default mod of operation. The other parameters are not valid for operation with the BB701. They are only listed for the sake of complete documentation of the controller. 1. Press the key to enter the programming mode. -
Page 14: Target Plate Air Purge
BB701 Target Plate Air Purge The BB701 comes with a nitrogen air purge collar that surrounds the target plate. When connected to a nitrogen gas source the target plate is kept free of condensation at lower temperatures. Snow is likely to form on the plate when it is kept at temperatures below freezing temperature. -
