National Instruments PXIe-4082 PXI Digital Multimeter

The National Instruments PXIe-4082 (Part Number: 783131-01) is a 6½-Digit, ±300 V, Onboard 1.8 MS/s Isolated Digital Multimeter. This Multimeter provides the typical measurement capabilities found in a high-resolution DMM and a digitizer. As a DMM, the NI PXIe‑4082 delivers speedy, precise AC/DC voltage, AC/DC current, 2‑ or 4‑wire resistance, and frequency/period measurements, and diode tests. In the high-voltage, isolated digitizer mode, the PXIe‑4082 can acquire waveforms at sample rates of 1.8 MS/s maximum. The device has a frequency range of 15 Hz to 500 kHz.

The NI PXIe‑4082 features a 10 to 23-bit versatile resolution, voltage measurements up to 300 VDC (300 Vrms), current measurements up to 1 A, resistance measurements up to 100 MΩ, and basic capacitance and inductance measurement capabilities. It has a power consumption of +12 V load at 0.55 A maximum, and +3.3 V load at 0.55 A max.

For the isolated digitizer, the voltage of the National Instruments PXIe‑4082 PXI Digital Multimeter ranges from ±100 mV to ±300 V (DC or AC coupled), the current ranges from ±20 mA to ±1 A, and the sample rate range is 10 S/s to 1.8 MS/s. The front panel of the device has 4 shrouded banana plug connectors.

The NI PXIe-4082 PXI Digital Multimeter has a recommended operating temperature range of 0 0C to 55 0 C, a storage ambient temperature range of -40 °C to 71 °C, a relative humidity range of 10% to 90% (noncondensing) in an operating environment, and a maximum altitude is 2,000 m (800mbar) at 25 °C ambient temperature. The NI device weighs 12 oz, and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively – all at a frequency range of 5 Hz to 500 Hz.

The PXIe-4082 has a recommended warm-up time of 60 minutes to rated accuracy, and should be calibrated externally at least once In 2 years. It is run using the NI-DMM 15.2 or later driver software which is compatible with software packages or application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio.

The PXIe-4082 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PXIe-4082 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PXIe-4082 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
