Overview
National Instruments 4065 devices are low-cost 6
1

-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/V
rms
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

-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

and 7

digits with 1.8 MS/s digitizer capability for faster
sampling rates in production test environments.
Efficient Mixture of Accuracy, Resolution,
and Speed
NI 4065 DMMs offer 6
1
⁄

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

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.

-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

-digit FlexDMM devices. The PCI-4070 can accurately measure
100 readings/s at 6

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
