Packing List
Examine the shipping carton and the contents for physical
damage. The following items should be in the shipping carton:
1. FBDA module
2. This instruction manual
If any of these items are damaged or missing, contact B&B
Electronics immediately.
Software
Software is not included with the FBDA module. This device is
used in conjunction with a data acquisition device. All of B&B
Electronics’ data acquisition modules come complete with software
that you can modify to meet your exact needs.
Calibration
The FBDA is calibrated at the factory. The excitation
voltage is set to 5VDC ± 0.05VDC and the gain is calibrated at 80 ±
2. The process of calibrating the FBDA and your sensor will vary
depending on the type of sensor being used. An example calibration
procedure is covered in Chapter 3.
