CPH

4-bit unsigned data for compensation of phase error, 0°+0.576°.

16 values are possible with a compensation step of 0.0384°. When CPH=0 the

compensation is 0°, when CPH=15 the compensation is 0.576°.

CHV

8-bit unsigned data for voltage channel calibration.

256 values are possible. When CHV is 0 the calibrator is at -12.5% of the

nominal value. When CHV is 255 the calibrator is at +12.5%. The calibration

step is then 0.098%.

CHP

8-bit unsigned data for primary current channel calibration.

256 values are possible. When CHP is 0 the calibrator is at -12.5% of the

nominal value. When CHP is 255 the calibrator is at +12.5%. The calibration

step is then 0.098%.
