How do you know it is not using RMS? If it says NO2 that is RMS mode. There is no other indicator on the device while you are using it. Only way to tell would be to scope it or put it on an ECD meter.
After setting it for RMS mode when I go to set the watts, it is still in volt (AVG). Again, it shows 002 (with the bottom of the 0 darkened making it appear as an n)it stays in voltage (AVG) mode only letting me set V & not watts. It is working great but I have to play with the volt setting instead of watts which is why I purchased the Vamo.
