Software Utility 67
8.3 Calibration
This function takes you through the card calibration process. The
calibration program is a useful test for A/D, D/A, and DIO
functions, and a tool when troubleshooting the card.
NOTE For environments with frequent large fluctuations in tem-
perature and vibration, a re-calibration interval of 3
months is recommended. For laboratory conditions, 6
months to 1 year is acceptable.
When you select Calibration from the main menu, the
calibration screen appears.
After selecting a calibration item from the menu, a calibration
window appears. The upper window shows the step-by-step
calibration instructions. The lower window shows the layout of
PCI-9812/9810. In addition, the proper Variable Resistor (VR) will
blink to indicate which VR needs to be adjusted for the current
calibration step.
