🧭🧭🧭 TrueRMS AC measurement on budget
This is a tip for everyone with at least a low-expensive oscilloscope and does not have a TrueRMS DMM.
1️⃣ Your oscilloscope most probably contains a precise TrueRMS measurement engine.
2️⃣ Go to Measure or Quick measure tool and choose either Vrms or Crms preset.
3️⃣ What is the difference? I will tell you.
The Vrms preset calculates the RMS value from the entire captured waveform.
The Crms preset calculates the RMS value from the entire undivided waveform period or periods.
