Description
These constants control the gain of their respective channels. The nominal
value for each parameter is 2
proportional to its CAL parameter. Thus, if the gain of a channel is 1% slow,
CAL should be increased by 1%.
Gain control for V3 channel, used for neutral current measurement.
These three constants control the CT phase compensation. No compensation
occurs when PHADJ_X = 0. As PHADJ_X is increased, more compensation
(lag) is introduced. Range: ±2
angle Φ:
During calibration, the value of TEMP_RAW_X should be placed in
TEMP_NOM.
