In an ideal world the output from the AC sensing circuit would be proportional to
the AC current and voltage at its input for all voltage and current levels (within a
certain random accuracy).
In practice, the un-calibrated accuracy can vary as a function of the voltage or
current level (this is called a slope error) and/or be offset by a fixed amount
(offset error). This is shown in Figure 1 to Figure 3 below.
The point of calibration is to make the measured current and voltage equal to the
input voltage and current within a certain random error tolerance.
