Description

CAL_IA
16384
These constants control the gain of their respective channels. The nominal
value for each parameter is 2
14 = 16384. The gain of each channel is directly
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.
0x0E
PHADJ_A
0
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:
±215 – 1. If it is desired to delay the current by the
