    "Measured values are float32 input registers (FC04, two registers each, most significant byte first); at most 20 values per request.",
    "Energies are given here without a unit because the interface definition does not state it. The overflow counters count energy register rollovers.",
    "Registers marked for 3P4W, 3P3W or 1P2W read 0 on the other wiring systems (manual table 1).",
    "Models 1320/30/40 count import and export energy; the 2340 counts utility and generator energy. Values marked only 2340 are on the EM 2340 only; the THD registers are not on the 1320 and 1330.",
    "Not in this map: the 'old' (previous period) values, the values updated at the user update rate, the 4X copies and the setup registers."
