Issue Details

What is the minimum DC current value that my PXIe-4082 DMM can measure? 

Solution

As outlined in the PXIe-4082 specifications, the accuracy of the device is dependent on aperture time. At aperture times greater than 100ms, the values in Table 3 will be your limiting factor for measurement accuracy. For aperture times less than 100ms, reference Figure 3 to find the relevant noise value. As referenced by the note below the figure, multiply this value by 5 and add it to the value for the specified range in Table 3.
