  • This contribution adheres to CONTRIBUTING.md.
  • I've updated CHANGELOG.md if applicable.
  • I've added tests applicable for this pull request

What does this Pull Request accomplish?

  • Adds nidmm_max_dc_reading_rate_at_7_5_digits.py, a Python example based on the LabVIEW "Max DC Reading rate at 7.5 digits" VI. It configures an NI PXI-4071 or PXIe-4081 for continuous 7.5-digit DC voltage measurements with ADC calibration off, Auto Zero on, a fixed aperture in power line cycles and a set number of averages, then charts the readings live and reports the reading rate.
  • Adds the example to the NI-DMM examples documentation.

List issues fixed by this Pull Request below, if any.

None.

What testing has been done?

Manually validated with a simulated instrument and an actual hardware instrument.
