National Instruments 783131-01 PXI Digital Multimeter 

National Instruments part number 783131-01 is an identifying part number for the PXIe-4082, a PXI Digital Multimeter. The PXIe‑4082 is a PXI Digital Multimeter with 6 1⁄2-digit precision, is capable of handling voltages up to ±300 V. It has onboard 1.8 MS/s isolated digitizer functionality and supports L and C measurements. It provides accurate AC/DC voltage and current measurements, along with 2‑ or 4‑wire resistance, frequency, period, basic L and C measurements, and diode tests. 

The front panel of the device has 4 shrouded banana plug connectors. For the isolated digitizer function, the voltage range of the National Instruments PXIe‑4082 PXI Digital Multimeter spans from ±100 mV to ±300 V (DC or AC coupled), while the current ranges from ±20 mA to ±1 A and the sample rate range is from 10 S/s to 1.8 MS/s. This model offers a versatile resolution ranging from 10 to 23 bits. It supports voltage measurements up to 300 VDC (300 Vrms), current measurements up to 1 A, and resistance measurements up to 100 MΩ. Additionally, it provides basic capacitance and inductance measurement capabilities. 

The power consumption specifications include a maximum of 0.55 A for a +12 V load and a maximum of 0.55 A for a +3.3 V load. The PXIe-4082 requires a recommended warm-up time of 60 minutes to achieve rated accuracy and should undergo external calibration at least once every 2 years. It operates using the NI-DMM 15.2 or later driver software, which is compatible with software packages or application development environments (ADEs) like LabVIEW, LabWindows/CVI, or Measurement Studio. The maximum DC voltage component supported by the device is 250V. It consumes less than 9 watts from the PXI Express backplane. For power consumption, it draws a maximum of 0.55 A for both +12 V and +3.3 V loads.
