This is part 2 of the How True RMS and Averaging multi-meters work. <br />You find part 1 here: <a href="https://youtu.be/idrLOfgTceE" target="_blank" rel="nofollow">https://youtu.be/idrLOfgTceE</a><br /><br />This one: "Measuring RMS Voltages: How true is your True RMS multimeter really?" may also be of interest<br /><a href="https://youtu.be/jhy_kfhwwbo" target="_blank" rel="nofollow">https://youtu.be/jhy_kfhwwbo</a><br /><br />In this video I am showing the wave form analyser you can download from Github. <br /><a href="https://github.com/TheHWcave/RMS-Waveform-Analyser" target="_blank" rel="nofollow">https://github.com/TheHWcave/RMS-Waveform-Analyser</a><br /><br />The wave form analyser is a spreadsheet for Microsoft Excel or LibreOffice Calc and contains the models you see in the video plus a few more. The idea is that you can define your own wave form in 100 samples, by either typing amplitude values or using a mathematical formula. The spreadsheet will then:<br />- plot the values as they would look on a scope using DC or AC coupling and calculate <br />- the (AC+DC) True RMS, <br />- DC part (if any), <br />- the AC True RMS, <br />- and the value a non-true RMS (averaging) meter would show.<br />...<br /><a href="https://www.youtube.com/watch?v=eN1VN3f2378" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=eN1VN3f2378</a>
