The same data is available as 32-bit registers (7500-7786, one address per value) and in the byte order 1-0-3-2 (6000-6573); this map uses the 7000 and 7800 areas.", "Values the meter cannot give are returned as 1e20 (above range or error) or -1e20 (below range).", "Which values exist depends on the measurement mode (3Ph/4W, 3Ph/3W or 1Ph/2W). The manual has a column per mode; for 3Ph/3W the per-phase powers, voltages and power factors are not available.", "Energy is also in registers 4038-4049 as 32-bit integers in units of 100 Wh. The meter returns 1e20 when it cannot give a value; the manual does not say how the integer energy registers behave.", "Registers 1000-1077 hold the mean power archive (a window of 15 records); they are not listed here.", "Registers marked with firmware_min 1.09 exist from program version 1.09. Registers 4062-4068 are reserved."],
