    "Addresses are as sent on the bus (hex C550 is decimal 50512). Values are 32-bit, high word first; scaling is applied through the register scale.",
    "Only part of the manual's tables is mapped: main measurements, energies and the first average values. Pulse counters, maxima, harmonics and the old pre-2009 table are not included."
