National Instruments 8252 用户手册

•

Measurement Category IV is for measurements performed at the 
primary electrical supply installation (<1,000 V). Examples include 
electricity meters and measurements on primary overcurrent 
protection devices and on ripple control units.

The NI PCI-8252 ships in an antistatic package to prevent electrostatic 
discharge from damaging device components. To avoid such damage in 
handling the device, take the following precautions:

•

Ground yourself via a grounding strap or by holding a grounded object, 
such as the computer chassis.

•

Touch the antistatic package to a metal part of the computer chassis 
before removing the device from the package.

Never touch the exposed pins of connectors.

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 PCI-8252 in the antistatic package when not in use.

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 a list of 

the typical power requirements for the device.

1.

Install the NI-IMAQ for IEEE 1394 Cameras driver software before 
installing the NI PCI-8252 device. 

For information about how to install NI-IMAQ for IEEE 1394 Cameras, refer to the 

NI-IMAQ for IEEE 1394 Cameras Software Installation Guide.

2.

Power off and unplug the computer.

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 access to the expansion slots.

4.

Choose an unused PCI slot, and remove the corresponding expansion 
slot cover on the back panel of the computer.
