value is represented in two's complement notation and in the range of -1.0 ≤
right of the MSB. Negative values have no significance.
Address: 7 (Instantaneous Current); 8 (Instantaneous Voltage); 9 (Instantaneous Power)
I and V contain the instantaneous measured values for current and voltage, respectively. The instantaneous
voltage and current samples are multiplied to obtain Instantaneous Power (P). The value is represented in two's
complement notation and in the range of -1.0 ≤ I, V, P < 1.0, with the binary point to the right of the MSB.
Address: 10 (Active Power)
The instantaneous power is averaged over each computation cycle (N conversions) to compute Active Power
(P
