>>>>> Calibration
DEMO6: AD Calibration.

Note that the demo6 only used when the AD value is inaccurate, 
it can adjust the reference value of AD permanently. 
Each PCI-1002 Series card is already fully calibrated when shipped from the factory,
so it is usually unnecessary to calibrate the board again unless the accuracy is lost.
