Can only say, that your result isn’t correct for Austria (household).
They must be recalibrated every 5 years and so they are changed with no extension and the period 4-20 is wrong for household.
Maybe it includes all kinds and industry is done differently upto 20 years with extension period.
And we cant opt for a special meter, you have to take what the provider for your region will bring (there are many types possible even from one provider maybe more possibilities).
Thats making automatically reading (LED-interface) much more complicated for interested customers, as they may need different readers and you dont know what you will get before and may change in 5 years.
