AD12-8 Manual
Installing the AD12-8 Card
The following procedure will show you how to install the AD12-8 inside the computer.
1. Ensure that all options have been set as described in the first part of this chapter. Be sure to pay
close attention to base address selection.
2. Turn off the power switch of your computer and remove the power cords from the wall outlet.
CAUTION!
Failure to remove power from the computer could result in electrical shock, or
damage to your computer system.
3. Remove the computer cover.
4. Locate an unused full length slot, and remove the blank I/O back plate.
5. Insert the card in the slot, and install the I/O back plate screw.
6. Inspect the installation for proper fit and seating of the card.
7. Replace the computer cover.
8. Reapply power to the computer.
9. Perform the calibration procedure which follows.
Calibration and Test
All cards are calibrated prior to shipment. However, periodic calibration of AD12-8 is recom-
mended to retain full accuracy. The calibration interval depends to a large extent on the type of
service that the card is subjected to. For environments where there are frequent large changes of
temperature and/or vibration, a three-month interval is suggested. For laboratory or office condi-
tions, six months to a year is acceptable.
A 4-1/2 digit digital multimeter is required as a minimum to perform satisfactory calibration. Also,
a voltage calibrator or a stable noise-free DC voltage source that can be used in conjunction with
the digital multimeter is required.
Calibration is performed using the SETA12 program on the diskette supplied with your card. This
program will lead you through the set up and calibration procedure with prompts and graphic
displays that show the settings and adjustment trim pots. This calibration program also serves as
a useful test of the AD12-8 A/D functions and can aid in troubleshooting if problems arise.
