Documentation Number FBDA0797 Manual 

 

 

 

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.
