🧭🧭🧭 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.
…while…
The Crms preset calculates the RMS value from the entire undivided waveform period or periods.
