© National Instruments Corporation 25 NI Digital Multimeters Getting Started GuideAppendix B: Chassis Recommendations and System ConsiderationsThis appendix specifies the recommended chassis components and conditions for a system that includesNational Instruments DMMs.PXI Chassis RecommendationsThe NI PXI-4060/4065 and NI PXI-407x are designed to operate in any PXI-compliant chassis.Temperature on these DMMs can vary with slot position in the chassis. Complete the followingrecommendations to minimize this temperature variation and ensure normal operating conditions forthese DMMs:• Perform routine maintenance of the chassis cooling fan filters, including cleaning. Suchmaintenance ensures continuous cooling effectiveness, keeps dust off the components of the PXIDMMs, and ensures accurate high-resistance measurements. NI recommends cleaning the chassisfan filters at a maximum interval of six months and keeping the chassis environment clean tominimize dust that enters the chassis. For more information about cleaning the chassis fan filters,refer to your chassis documentation.• Install PXI filler panels in all empty slots.• Verify the PXI chassis fans that provide forced air remain unobstructed and can allow for propercooling of the PXI chassis, devices, and controller.PXI Express ChassisSome PXI Express chassis provide hybrid slots. A hybrid slot can accept either PXI Express modulesor PXI Express compatible modules, but not standard PXI modules.To determine if your chassis contains hybrid slots, refer to your chassis documentation. For moreinformation about hybrid slots, visit ni.com/support, and enter PXI Express FAQ in the Searchfield.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 aboutPXI Express compatibility.PCI Chassis RecommendationsThe NI PCI-4060, NI PCI-4065, and NI PCI-4070 are designed to operate in any ATX-compliantindustrial or personal computer. Complete the following recommendations to ensure normal operatingconditions 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 havea firm, direct, metal-to-metal mounting connection for proper grounding. Some computermanufacturers 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 doesnot 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. |
