Table 61: CE Calibration Parameters
Description
These constants control the gain of their respective channels. The
nominal value for each parameter is 2
channel is directly proportional to its CAL parameter. Thus, if the
gain of a channel is 1% slow, CAL should be increased by 1%.
These constants control the CT phase compensation. No com-
pensation occurs when PHADJ_X = 0. As PHADJ_X is increased,
more compensation (lag) is introduced. The range is
is desired to delay the current by the angle
These parameters are added to compensate for input noise and
truncation in their respective channels in the squaring calcula-
tions for I
