The Reactive Power (Q ) is calculated using trigonometric identities. (See Section 4.3 Power Measurements
Trig
on page 14). The value is represented in unsigned notation and in the range of 0 ≤ S < 1.0, with the binary point
to the right of the MSB.

Power Factor is calculated by dividing the Active (Real) Power by Apparent Power. The value is represented in
two's complement notation and in the range of -1.0 ≤ PF< 1.0, with the binary point to the right of the MSB.
