Overview
The National Instruments 4070 FlexDMM is a 6

-digit digital multimeter
that achieve remarkable throughput rates while maintaining precision and
stable measurement accuracy. With National Instruments proprietary
FlexDMM technology, these DMMs also provide a fully isolated, high-
voltage digitizer, capable of acquiring waveforms at sampling rates up to
1.8 MS/s at all voltage and current values. Using the analysis functions
in National Instruments LabVIEW, you can analyze these waveforms in
both the time and frequency domains. The NI 4070 DMMs have superior
speed, accuracy, and functionality, making them an excellent fit for use in
automated tests on both the production floor and in an R&D environment.

Software
• NI-DMM is an IVI-compliant driver that accesses the complete
functionality of the DMM through an easy-to-use application
programming interface (API).
• Compatible languages include C/C++, .NET, Visual Basic, LabVIEW,
and LabWindows/CVI.

• Users can vary the resolution of the FlexDMM from 10 to 23 bits
by simply changing the sampling rate, as reflected in Figure 1.
• The unique multi-instrument functionality minimizes overall system
cost by eliminating the need to purchase a separate data acquisition
device, signal conditioning, fixturing, and so on.

• Self-calibration (Self-Cal) improves accuracy by removing errors due to
temperature variation and long-term drift.
• Self-Cal ensures accuracy over entire 0 to 55 °C operating range.
• 2-year external calibration cycle reduces downtime and maintenance costs.
