• Perform routine maintenance of the chassis cooling fan filters, including cleaning. Such maintenance ensures continuous cooling effectiveness, keeps dust off the components of the PXI DMMs, and ensures accurate high-resistance measurements. NI recommends cleaning the chassis fan filters at a maximum interval of six months and keeping the chassis environment clean to minimize dust that enters the chassis. For more information about cleaning the chassis fan filters, refer to your chassis  ocumentation.
• Install PXI filler panels in all empty slots.
• Verify the PXI chassis fans that provide forced air remain unobstructed and can allow for proper cooling of the PXI chassis, devices, and controller.

PXI Express Chassis
Some PXI Express chassis provide hybrid slots. A hybrid slot can accept either PXI Express modules or PXI Express compatible modules, but not standard PXI modules.
To determine if your chassis contains hybrid slots, refer to your chassis documentation. For more information about hybrid slots, visit ni.com/support, and enter PXI Express FAQ in the Search field.
Refer to the PXI Express Compatibility section of the NI Digital Multimeters Help, located at Start» All Programs»National Instruments»NI- DMM»Documentation»NI Digital Multimeters Help, to determine if your DMM is PXI or PXI Express compatible and for more information about PXI Express compatibility.

PCI Chassis Recommendations
The NI PCI-4060, NI PCI-4065, and NI PCI-4070 are designed to operate in any ATX-compliant industrial or personal computer. Complete the following recommendations to ensure normal operating conditions for these DMMs:
Caution For optimal electromagnetic compatibility (EMC) performance and input protection, you must install the front panel screw.

• Verify the PCI front panel brackets on the NI PCI-4060, NI PCI-4065, and NI PCI-4070 have a firm, direct, metal-to-metal mounting connection for proper grounding. Some computer manufacturers use a securing lever made of plastic; such a lever is  unacceptable for safety reasons, and you must remove it. Also, you must screw down the PCI devices. If the computer chassis does not allow you to meet these requirements, you must use a different computer chassis.
• Install all covers for the industrial chassis or personal computer.
• Install PCI filler panels in all unused PCI slots.

Additional Recommendations for the NI PCI-4070
The cooling capability of most industrial and personal computers is less than the cooling capability of a PXI chassis. The NI PCI-4060 and the NI PCI/PCIe-4065 dissipate low enough power that additional cooling is not needed in most computers. The NI PCI-4070 dissipates higher power, and NI strongly recommends NI PCI-4070 users implement the following precautions to maximize the cooling capability of the computer:

• Install an additional 80 mm, 32 cubic ft/min (CFM) fan that forces air towards the NI PCI-4070.
  Most computer chassis contain one or two mounting locations for this type of fan. These fans are inexpensive and readily available at most computer supply stores.
  Note If the hard drive mounts vertically in front of the fan mounting location(s) in the computer chassis, you must move the hard drive to a horizontal 3.5 in. drive bay or to another suitable location that does not obstruct the fan mounting location(s).

• Add additional fans, such as PCI fan cards and chassis fans, to increase the air circulation inside the computer.

USB System Considerations
The NI USB-4065 conforms to USB 2.0 specifications and is 1.1 compliant. The NI USB-4065 is a high powered USB device that supports both Hi-Speed and full- speed USB protocol. For more information about power requirements, refer to the NI 4065 Specifications.
