Appendix C Calibration
PCI-1711U 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 the Advantech Device Manager on the companion CD-ROM
to assist you with D/A and A/D calibration. The Advantech Device Man-
ager makes calibration easy. With a variety of prompts and graphic dis-
plays, 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.
The Advantech Device Manager can be accessed through the Start button:
Start/Programs/Advantech Automation/Device Manager/Advantech

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.
