Taking Measurements with NI Digital Multimeters

At the end of this course, you will be able to recognize different specifications from NI Digital Multimeters (NI-DMM), allowing you to select an instrument and the best-suited probes for your measurement needs. You will have explored the setup of an NI-DMM device and explored both interactive and programmatic measurements of a DUT. This course also prepares you to explore different capabilities of the NI-DMM driver such as measuring inputs and operating your DMM with other instruments in a system.
