National Instruments (NI) recently introduced a new high-performance digital multimeter, the PXIe-4082, model number 783131-01. The 6½ bit 300V digital multimeter integrates high-resolution DMM (Digital Multimeter) and digitizer measurement capabilities to provide users with a fast and accurate measurement experience.

When used as a digital multimeter, the PXY-4082 is capable of AC/DC voltage, AC/DC current, 2-wire or 4-wire resistance, frequency, period, and basic capacitance and inductance measurements, as well as diode testing. In high voltage isolated digitizer mode, the device is capable of acquiring waveforms at a sample rate of 1.8 MS/s, covering a frequency range of 15 Hz to 500 kHz.

This digital multimeter has A multifunctional resolution of 10 to 23 bits and is capable of voltage measurement up to 300 VDC (300 Vrms), current measurement up to 1 A, and resistance measurement up to 100 mΩ. In addition, it has basic capacitance and inductance measurement capabilities, and has an isolated digitizer with voltage ranges from 100 mV to 300 V (DC or AC coupling), current ranges from 20 mA to 1 A, and sampling rates from 10 S/s to 1.8 MS/s.

PXIE-4082

The front panel of the PXIe-4082 is equipped with 4 shielded banana plug connectors, ensuring the stability and security of the connection. The recommended operating temperature range of the device is 0°C to 55°C, the storage environment temperature range is -40°C to 71°C, the relative humidity range is 10% to 90% (non-condensing), and the maximum altitude at 25°C is 2000 meters.

National Instruments recommends a warm-up time of 60 minutes for the PXIe-4082 to achieve rated accuracy, and recommends external calibration at least once every 2 years. Device operation requires the use of NI-DMM 15.2 or later driver software that is compatible with packages or application development environments such as LabVIEW, LabWindows/CVI or Measurement Studio.

The introduction of the PXIe-4082 marks another important advance in the field of industrial automation and test and measurement, providing engineers and researchers with a high-performance, high-precision measurement tool.
