Sadly, long-pressing doesn’t seem to do it either. :(

It would be nice to have an “indicator” stating that it is being calculated as Vrms though (especially in the logs as currently, there’s no way to distinguish between 24VDC(rms) and 24VDC(non-rms).

Of course, a Peak/min hold feature would be nice too but now I’m just adding to the feature request :D
