3.4 Harmonic Analysis Output Quantities
The start address is 0x20088348. The Metrology module generates the following primary output measurement quantities for each measurement interval, per-phase quantities with each phase designated by the subscript “_x” (where x = [A, B, C] for voltage channels and x = [A, B, C, N] for current channels).
Internal scaling allows accurate harmonic analysis for integration periods of up to 16 seconds for up to full-scale magnitude input waveforms.
