A.GND.

A calibration utility is included with the ADLINK CD, which is included with the
product package. A detailed calibration procedure and description can be
found in the utility. Users only need to run the software calibration utility and
follow the procedures.
Note: When you first receive the PCI-9112 card, calibration is NOT
necessary, the PCI-9112 has been fully calibrated before it is
shopped.
