Getting Started with the NI PCI-8252
•
Measurement Category II is for measurements performed on circuits directly connected to the
electrical distribution system. This category refers to local-level electrical distribution, such as that
provided by a standard wall outlet (e.g., 115 V for U.S. or 230 V for Europe). Examples of
Measurement Category II are measurements performed on household appliances, portable tools,
and similar products.
•
Measurement Category III is for measurements performed in the building installation at the
distribution level. This category refers to measurements on hard-wired equipment such as
equipment in fixed installations, distribution boards, and circuit breakers. Other examples are
wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation,
and stationary motors with permanent connections to fixed installations.
Unpacking
The NI 8252 ships in an antistatic package to prevent electrostatic discharge from damaging device
components. To avoid such damage in handling your device, take the following precautions:
1.
Ground yourself using a grounding strap or by touching a grounded object, such as the computer
chassis.
2.
Touch the antistatic package to a metal part of the computer chassis before removing the device
from the package.
Caution
Never
touch the exposed pins of connectors.
3.
Remove the device from the package and inspect it for loose components or any other signs of
damage. Notify National Instruments if the device appears damaged in any way. Do
not
install
a damaged device in the computer.
Store the NI 8252 in the antistatic package when not in use.
Installation
The following instructions are for general installation. Refer to the documentation provided by your
computer manufacturer for specific instructions and warnings. Refer to the
section for
typical power requirements for the NI 8252.
1.
Install the NI Vision Acquisition Software before installing the NI 8252. Refer to the
NI Vision
Acquisition Software Release Notes
for specific installation instructions.
2.
Power off and unplug the computer.
Caution
To protect yourself and the computer from electrical hazards, the computer
must
remain
unplugged until the installation is complete.
3.
Remove the computer cover to expose the expansion slots.
4.
Touch a metal part of the computer to discharge any static electricity that might be on your clothes
or body. Static electricity can damage the device.
5.
Choose an unused PCI slot, and remove the corresponding expansion slot cover on the back panel
of the computer.
6.
Remove the NI 8252 device from the antistatic package and gently rock the device into the slot.
The connection may be tight, but do
not
force the device into place.
Note
Check that the bracket of your device aligns with the hole in the back panel rail of the
computer chassis.
7.
Secure the device mounting bracket to the back panel rail of the computer.
