KPCI-3101 — KPCI-3104 Series User’s Manual
NOTE
The analog input test is a software function test, not a calibration check,
although readings from a properly calibrated board should correspond
to a known test voltage within the accuracy specifications of the board.
If you wish to check and adjust the accuracy, refer to
,
“
.”
NOTE
The analog input software test is only a basic check of your application
software. You are encouraged to perform additional tests that exercise
your software more thoroughly.
Equipment for the analog input software test
The following equipment is needed for the analog input test:
•
A voltage source supplying a known voltage at <5V. Refer to
for more details.
•
(Optional) A Digital Voltmeter (DVM) or a Digital Multimeter (DMM) to accurately deter-
mine the voltage of the voltage source.
•
An STA-300 screw terminal accessory wired as shown in
. This is the same wiring
scheme as used in the analog input hardware tests.
•
If possible, use a screw terminal accessory that is reserved for I/O tests. Avoid using a screw
terminal accessory that is normally connected to your external circuits. You thereby avoid the
extra labor and potential wiring errors involved in disconnecting and later reconnecting your
external circuits.
CAUTION
If you use the +5V board power to energize a voltage divider, ensure
that the +5V board power terminal cannot accidentally short to
ground. A short to ground can damage one or more of the following:
the screw terminal accessory, the board, the computer.
