PCI-1718 Series User Manual 82
Appendix D Calibration
PCI-1718 cards are calibrated at the factory for initial use. However, a
recalibration of the analog input and the analog output function is recom-
mended:
1. Every six months.
2. Everytime the analog output range is changed.
We provide a calibration program on the companion CD-ROM to assist
you with D/A calibration. The calibration programs make calibration an
easy job. With a variety of prompts and graphic displays, these programs
will lead you through the calibration and setup procedures, showing you
all the correct settings and adjustments.
To perform a satisfactory calibration, you will need a 4½-digit digital
multi-meter and a voltage calibrator or a stable, noise-free DC voltage
source.
This calibration utility is designed for the Microsoft
© DOS environment.
Access this program from the default location:
\Program Files\Advantech\ADSAPI\Utilities\PCI-1718
Note: If you installed the program to another directory,
you can find these programs in the corresponding
subfolders in your destination directory.
Note: Before you calibrate the D/A function, you must
turn on the power at least 15 minutes to make sure
the DA&C card is already stable.
