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% low, CAL should be increased by 1%.

PHADJ_A
0
These constants control the CT phase compensation. No
compensation occurs when PHADJ_X = 0. As PHADJ_X is increased,
more compensation (lag) is introduced. The range is
± 215 – 1. If it
is desired to delay the current by the angle
Φ, the equations are:

Note:
The current sensor inputs are not assigned to the A, B and C phases in a fixed manner. The
assignments of phases A, B and C depends on how the IADC0-1, IADC2-3, IADC4-5, IADC6-7 current
sensing inputs are connected in the meter design. The CE code must be aware of these connections.
See Figure 31 and Figure 32 for typical meter configurations. VADC8, VADC9 and VADC10 are
assigned to voltage phases VA, VB and VC in a fixed manner, respectively.
The CE addresses listed in this table are assigned to phases A, B and C as indicated by their names.
