This register contains gain coefficient for phase X fundamental energy. The raw values are taken from the selected
measurement quantity and scaled by the following factor:
This signed register contains the linearity offset for phase X current channel when the programmable gain amplifier
is set to unity gain (that is, the measured current is above the low current threshold). The signed value represented
by this register is added to the current value according to following formula:
This register contains the linearity coefficient for phase X current channel when the programmable gain amplifier is
set to gain of 32 (that is, the measured current is below the low current threshold). The effective gain is given by the
equation:
