Part Number: 783131-01

The National Instruments PXIe-4082, identified by part number 783131-01, is a high-performance PXI Digital Multimeter designed for precision measurements in industrial automation and control applications. This instrument offers 6.5-digit resolution and can measure voltages up to ±300 V, making it suitable for a broad range of applications. It features an onboard isolated digitizer with a sampling rate of up to 1.8 MS/s, supporting advanced L and C measurements alongside standard AC/DC voltage and current measurements. The PXIe-4082 also facilitates 2- and 4-wire resistance measurements, frequency and period measurements, as well as diode testing.

The device is equipped with four shrouded banana plug connectors on the front panel for secure connections. Its voltage measurement capabilities range from ±100 mV to ±300 V (DC or AC coupled), with current measurement options spanning ±20 mA to ±1 A, and a resistance measurement capability of up to 100 MΩ. Additional features include fundamental capacitance and inductance measurement functionalities, which enhance its versatility in various testing scenarios.

For optimal performance, the PXIe-4082 requires a warm-up time of 60 minutes to achieve rated accuracy and should be calibrated externally at least once every two years. The device operates with NI-DMM driver software (version 15.2 or later), ensuring compatibility with various software packages and application development environments, including LabVIEW, LabWindows/CVI, and Measurement Studio. It is designed for efficiency, drawing less than 9 watts from the PXI Express backplane, with a maximum of 0.55 A for both +12 V and +3.3 V loads. The PXIe-4082 is a robust and versatile digital multimeter, ideal for detailed and accurate measurements in complex automated systems.
