6.4 Calibration Utility
The calibration utility,AutoCali, provides four functions - auto A/D
calibration, auto D/A calibration, manual A/D calibration and manual D/
A calibration. The program helps the user to easily finish the calibra-
tion procedures automatically; however, the user can calibrate the PCI-
1712/1712L manually. Sections 6.2 and 6.3 illustrated the standard
calibration procedures for your reference. If you want to calibrate the
hardware in your own way, these two sections will guide you.
The following steps will guide you through the PCI-1712/1712L
software calibration.
Step 1: Access the calibration utility program AutoCali.exe from the
default location:
C:\Program Files\Advantech\ADSAPI\Utility\PCI1712
Note:
✎ If you installed the program to another directory, you can find this
program in the corresponding subfolders in your destination directory.
Step 2: Select PCI-1712/1712L in the ADSDAQ dialog box.
