Voltage Gain, Phase X = A/B/C (X.V_GAIN) (A: 0x132, B: 0x21E, C: 0x30A)

This register contains gain coefficient for phase X voltage channel. The raw values are taken from the selected mea-

surement quantity and scaled by the factor:

Note: Bit 15 of this register must be set to zero for correct operation.

Energy Gain, Phase X = A/B/C (X.E_GAIN) (A: 0x134, B: 0x220, C: 0x30C)

This register contains gain coefficient for phase X energy. The raw values are taken from the selected measurement

quantity and scaled by the factor:

Note: Bit 15 of this register must be set to zero for correct operation.

Phase-Angle Compensation, High Range, Phase X = A/B/C (X.PA0)

(A: 0x13E, B: 0x22A, C: 0x316)

This signed register contains the angle as a fraction of one radian to add to the measured phase angle when the

measured current is above the value given in I1THR. This signed value ranges from -0.5 radian (at a value of

0x8000) to +(0.5 - 2-16) radian (at a value of 0x7FFF).
