They are ideally suited for OEMs, educational laboratories, or other cost-conscious test and measurement facilities. With ±300 VDC/Vrms of isolation, current measurements up to 3 A, and 2- or 4-wire resistance measurements, NI 4065 DMMs provide a complete multimeter solution for basic 6 1⁄2-digit measurement needs. For higher-performance requirements, consider using NI 407x PCI and PXI FlexDMM devices. They combine industry-leading accuracy and resolution at 6 1⁄2 and 7 1⁄2 digits with 1.8 MS/s digitizer capability for faster sampling rates in production test environments. Flexible Software Improves Usability You can program NI 4065 DMMs through a standard application programming interface (API) in NI LabVIEW and LabWindows/CVI or Microsoft programming languages. For simple benchtop measurements, the NI-DMM Soft Front Panel provides the common display and interface found on traditional DMMs to make simple measurements quickly and easily. When combined with switches, the DMM/Switch Express VI can rapidly develop a high-channel-count data-logging system with a single function call in LabVIEW. In LabVIEW SignalExpress, the DMM/Switch Express VI sets up a live data logger without any programming. Efficient Mixture of Accuracy, Resolution, and Speed NI 4065 DMMs offer 6 1⁄2 digits of resolution at up to 10 readings/s and up to 3000 readings/s at lower resolutions. By trading off speed for resolution, you can maximize measurement quality and throughput. NI 4065 DMMs also offer comparable accuracy over a 24-hour cycle or one year of an external calibration to other GPIB, LAN, or USB-based Table 1. NI 4065 Reading Rates versus Resolution 6 1⁄2-digit DMMs on the market. With an NI 4065, there is no need to sacrifice basic measurement quality for a low selling price. For higher resolution, accuracy, or speed, consider using one of the NI 407x 6 1⁄2-digit FlexDMM devices. The PCI-4070 can accurately measure 100 readings/s at 61⁄2 digits with 31 ppm of DC voltage accuracy over a two-year period. This represents a 3X improvement over the NI 4065 DMMs for accuracy and noise. The PXI-4071 is also available with measurements at 7 1⁄2 digits up to 1000 V.

Integration with Switching NI PXI-4065 You can easily combine the NI PXI-4065 DMM with NI PXI switches in the low-cost NI PXI-1033 integrated chassis and controller to create highchannel-count, 6 1⁄2-digit data-logging systems with up to 588 channels. You can configure these systems, controllable from any PCI Express or ExpressCard slot on a PC or laptop computer, with more than 100 available PXI switch topologies. For further system expansion, you can add more than 3,000 channels with each additional 18-slot PXI chassis. Figure 3. Use the USB-4065 with USB-controlled switching for a complete...
