Q: In the specifications, it states, “Range or Function Changes = 10/s.” What are the range or function changes?

For the PXI-4071, the voltage/current range or the function can be changed during execution. The rate at which it can be changed is two times per second maximum.

Q: Can the PXI-4071 be used to measure voltage higher than 10 V?

When the DMM is configured for the 10 V input range, the signal must remain within +/- 10.5 VDC.

Q: How can you configure the input resistance when using the PXI-4071 in a VI?

The DMM can be configured by using a property node.

National Instruments PXI-4071 PXI Digital Multimeter

The NI PXI-4071 (Part Number: 778271-01) is a FlexDMM, multifunction 3U PXI module that gives the estimation ability found in a high-resolution digital multimeter (DMM) and a digitizer. As a DMM, the PXI-4071 makes quick, precise voltage estimations from ±10 nV to 1000 V, current estimations from ±1 pA to 3 A, resistance estimations from 100 Ω to 5 GΩ, and takes recurrence/period and diode estimations. The device has a DC current range of -3 A to 3 A. In the high-voltage, confined digitizer mode, the PXI-4071 can get DC-coupled waveforms at test rates up to 1.8 MS/s in all voltage and current modes. Utilizing the examination capacities in NI LabVIEW programming, the user can study these waveforms in time and recurrence. The PXI-4071 offers prevalent speed, exactness, and usefulness, making it a great choice for use in robotized tests.

This model outperforms traditional 7 1/2-digit DMM speed/execution boundaries by utilizing a modern architecture that exploits the fast PXI bus. At 7 1/2 digits, the PXI-4071 accomplishes DC reading rates of 7 S/s. For applications requiring higher throughput, it has a high DC reading rate of 10 kS/s at 4 1/2 digits (these rates are no less than five times quicker than the original GPIB-controlled DMMs). The device, when AC coupled, has an auto-range time of 250 ms (for both AC V and AC I), a range/function change of 10/s, and a trigger latency and maximum trigger rate of 2 µs and 1 kHz, respectively. The device has a warm-up time of 1 hour before operation.

The PXI-4071 can import and export triggers, making it simple to coordinate them with any multiplexer/matrix switch modules. Specifically, the FlexDMM incorporates consistently with National Instruments' switch offerings. For example, with NI switch modules and NI Switch Executive switch management software, the user can quantify a huge number of channels, consisting of voltages, thermocouples, RTDs, and thermistors. The user can also keep a firm control on the cost of their framework.

Additional specifications for the PXI-4071 can be found in the datasheets and manuals under the "Manuals & PDFs" tab.

Apex Waves stocks end-of-life NI hardware for purchase and repairs in perpetuity. While the PXI-4071 is no longer available with National Instruments, the digital multimeter will remain available with us!

National Instruments PXI-4071 Frequently Asked Questions

Question: Does the NI DMM 3.0.5 driver support the PXI-4071?

Answer: Yes, the digital multimeter is supported by the NI DMM 3.0.5 driver.

Question: My NI PXI-4071 is failing when I run a self-test in Measurement & Automation Explorer. The error that appears is Error -223911. What does this mean and how do I prevent this error?

Answer: Error -223911 occurs after the DM module alias is renamed. This can be prevented by restarting Measurement & Automation Explorer (MAX) after every rename.

Question: In the specifications, it states, “Range or Function Changes = 10/s.” What are the range or function changes?

Answer: For the PXI-4071, the voltage/current range or the function can be changed during execution. The rate at which it can be changed is two times per second maximum.

Question: What do the 7.5 digits of resolution for the PXI 4071 mean?

Answer: The digits of resolution indicate the quantity of digits displayed on the DMM’s reading. For 7 digits, this means 0000000 ~ 9999999 can be displayed. For 7.5 digits, this can be displayed when 00000000 ~ 19999999 is displayed. If ½ is used for the digits, it is used when the first digit is represented by only 0 or 1.

Question: What is the range of the PXI-4071?

Answer: The digital multimeter offers voltage measurements from ±10 nV to 1000 V, current measurements from ±1 pA to 3 A, and resistance measurements from 10 mΩ to 5 GΩ.

Question: Can the PXI-4071 be used to measure voltage higher than 10 V?

Answer: When the DMM is configured for the 10 V input range, the signal must remain within +/- 10.5 VDC.

Question: How can you configure the input resistance when using the PXI-4071 in a VI?

Answer: The DMM can be configured by using a property node.
