    It will probably detect this and continuously display an indication that fraud has been detected.

    It was (sort of) a tongue in cheek question, but I imagine you're right.

    What about an analogue meter?

    Edit: It would just work as normal wouldn't it? Because it's AC.

    Many analogue meters will run backwards if the wiring is swapped.

    Digital ones will have some visual indication such as 'rED' in the display (for reverse energy detected) or illuminate the LED a different colour such as green, so that when the meter is next read, the fraudulent use can be detected.

    Very common to see such indicators now in ordinary use where solar panels are installed.

    Hi, it should not be possible to zero the meter as this is prohibited by the MID (Measuring Instruments Directive (MID 2014/32/EU) annex 1 section 8.5 if you really want to know).
