Example Configurations:
- Reducing Noise: Use longer aperture times for enhanced noise rejection in environments susceptible to 50 Hz interference.
- Improving Speed: Opt for default settings if high-speed measurements are critical, but can accept more noise.
C++-Style Pseudo Code Example:
MyDMM.powerLineFrequency = 50;
MyDMM.ApertureTimeUnits = DmmApertureTimeUnits.PowerLineCycles; // Default setting
MyDMM.ApertureTime = 1.0; // Equivalent to 1/50 Hz or 20 ms for noise suppression.
See NI-DMM Help for the exact usage of commands. You can find this file on your computer with a NI-DMM Driver installation, typically in this folder:

LabVIEW Example:
In LabVIEW, there is an example Improve DC Noise Rejection which shows a way to implement it. You can access this example via the NI Example Finder.
