How True RMS and Averaging multi-meters work: Part 1

In this video I am showing what RMS is, how to find out whether you have a True RMS or Averaging multi-meter and how they work.

This one: "Measuring RMS Voltages: How true is your True RMS multimeter really?" may be of interest. https://youtu.be/jhy_kfhwwbo

There is a part 2 where I am testing True RMS and Averaging meters against different wave forms with the help of a wave form analyser you can download from here: https://github.com/TheHWcave/RMS-Waveform-Analyser ... https://www.youtube.com/watch?v=idrLOfgTceE
