Fundamental Reactive Power (Q ) is calculated by performing a discrete Fourier transform (DFT) at the relevant
H
frequency on the V and I channels. The value is represented in two's complement notation and in the range of
-1.0 ≤ Q < 1.0, with the binary point to the right of the MSB.

Default = 0x34E2E7 = 26.443169
Sets the temperature channel gain. Temperature gain (T
) is utilized to convert from one temperature scale
Gain
to another. The Celsius scale (oC) is the default. Values will be within in the range of 0 ≤ T
< 128. The value
Gain
is represented in unsigned notation, with the binary point to the right of bit 7th MSB. See Section 5.7 On-chip
Temperature Sensor on page 19.

Default = 0xF3E7D0 = -0.094488
Temperature offset (T ) is used to remove the temperature channel’s offset at the zero degree reading. Values
off
are represented in two's complement notation and in the range of -1.0 ≤ Toff < 1.0, with the binary point to the
right of the MSB.
