4.10 Power Offset
The power offset registers, P1
to offset erroneous power sources resident in the sys-
tem not originating from the power line. Residual power
offsets are usually caused by crosstalk into current
paths from voltage paths or from ripple on the meter or

chip’s power supply, or from inductance from a nearby
transformer.
These offsets can be either positive or negative, indicat-
ing crosstalk coupling either in phase or out of phase
with the applied voltage input. The power offset regis-
ters can compensate for either condition.
To use this feature, measure the average power at no
load using either Single or Continuous Conversion com-
mands. Take the measured result (from the P1
