Power Offset (P
used to offset contributions to the energy result that are caused by undesirable sources of energy that are in-
herent in the system. The value is represented in two's complement notation and in the range of -1.0 ≤ P

is represented in unsigned notation, with the binary point to the right of bit 5.
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
The instantaneous power is averaged over each computation cycle (N conversions) to compute Active Power
