Unexpected capabilities in the DMM enable fast waveform capture of complex IoT power consumption. The inexpensive DMM is probably already on your bench and can give 4.5 digit measurements up to 50,000 readings per second, making it suitable for characterization of the dynamic nature of DC current being used by a IoT device less expensively than purpose-built instruments. This video displays the strengths and weaknesses of using DMMs and demonstrates the usefulness of DMM digitizing modes for measuring fast changing signals.
