REGISTER 3-32:
Phase y active power gain to produce X W/LSB. The value is always less than one (for
example, 32,767 = 0.9999695).
REGISTER 3-33:
Phase y apparent power gain so that all results can be calibrated to produce equal VA
hours. The signed 16-bit number produces a change in the PHy_VA_RAW value before
being added to the energy registers. A value of 32,767 represents a 99.9939%
increase while a value of 8192 represents a decrease of 50%.
REGISTER 3-34:
Phase y apparent power gain to produce X 0.1 mVA/LSB. The value is always less than
one (for example, 32,767 = 0.9999695).
