Low-Cost 61⁄2-Digit Multimeters NI PXI-4065, NI PCI-4065, NI PCIe-4065, NI USB-4065 NEW! • Basic 6 1⁄2-digit digital multimeters (DMMs) for PXI, PCI, PCI Express, and USB • 7 built-in measurement modes – AC/DC voltage, AC/DC current, 2- or 4-wire resistance, and diode test • ±300 VDC/Vrms isolation • 10 readings/s maximum at 61⁄2 digits • Ideally suited for OEMs, educational labs, and production test For increased accuracy, resolution, measurement speed, and functionality, consider NI 407x FlexDMM devices. 1PXI-4065 Operating Systems • Windows Vista/XP/2000 Recommended Software • • • • • LabVIEW LabVIEW Real-Time Module1 LabWindows™/CVI Measurement Studio LabVIEW SignalExpress Other Compatible Software • Microsoft Visual Basic • C/C++ Driver Software (included) • NI-DMM • NI-DMM Soft Front Panel • DMM/Switch Express VI Overview National Instruments 4065 devices are low-cost 6 1⁄2-digit PXI, PCI, PCI Express, and USB DMMs for the measurement of voltage, current, and resistance, or for diode test. 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...
