Analog input software test

This basic analog input test checks whether your application software correctly monitors DC
analog inputs. You ground analog channel 0, apply a DC voltage to channel 1, and measure the
results.

NOTE

During this test, ensure that no user circuits are connected to the
KPCI-3110 or KPCI-3116 board, via the required screw terminal acces-
sory, except for analog input connections specified for the test.

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

Section 5

,

“

Calibration

.”

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

Table C-5

for more details.

•

(Optional) A Digital Voltmeter (DVM) or a Digital Multimeter (DMM) to accurately deter-
mine the voltage of the voltage source.

•

An STP-3110 screw terminal accessory wired as shown in

Table C-5

. 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
