Okay, I think I can do this. On the other hand, any reasonable mains-powered voltmeter has to have an isolated PSU section which powers the input dividers/amplifiers and ADC, so that the measurement potential could be unrelated to the digital section with all the user and communication IO - which is needed to be earthed or somewhere close to that potential. This one calls for either DC or AC power, but it could be combined by having a PSU operating from an…
