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

Device Manager/

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.
