Description
PGA Gain Register. This register is used to adjust the gain selection for the PGA in
the current and voltage channels (see the Analog Inputs section).
Phase A VRMS Gain Register. The range of the voltage rms calculation can be
adjusted by writing to this register. It has an adjustment range of ±50% with a
resolution of 0.0244%/LSB.
Phase B VRMS Gain Register.
Phase C VRMS Gain Regsiter.
Phase A Current Gain Register. The range of the current rms calculation can be
adjusted by writing to this register. It has an adjustment range of ±50% with a
resolution of 0.0244%/LSB. Adjusting this register also scales the watt and VAR
calculation. Not for use with Mode 0 of CONSEL, COMPMODE[0:1].
Phase B Current Gain Register.
Phase C Current Gain Regsiter.
Phase A Watt Gain Register. The range of the watt calculation can be adjusted by
writing to this register. It has an adjustment range of ±50% with a resolution of
0.0244%/LSB.
Phase B Watt Gain Register.
Phase C Watt Gain Register.
Phase A VAR Gain Register.The range of the VAR calculation can be adjusted by
writing to this register. It has an adjustment range of ±50% with a resolution of
0.0244%/LSB.
Phase B VAR Gain Register.
Phase C VAR Gain Register.
Phase A VA Gain Register. The range of the VA calculation can be adjusted by
writing to this register. It has an adjustment range of ±50% with a resolution of
0.0244% / LSB.
Phase B VA Gain Register.
Phase C VA Gain Register.
Phase A Voltage RMS Offset Correction Register.
Phase B Voltage RMS Offset Correction Register.
Phase C Voltage RMS Offset Correction Register.
Phase A Current RMS Offset Correction Register.
Phase B Current RMS Offset Correction Register.
Phase C Current RMS Offset Correction Register.
Phase A Watt Offset Calibration Register.
Phase B Watt Offset Calibration Register.
Phase C Watt Offset Calibration Register.
Phase A VAR Offset Calibration Register.
Phase B VAR Offset Calibration Register.
Phase C VAR Offset Calibration Register.
Phase A Phase Calibration Register. The phase relationship between the current
and voltage channel can be adjusted by writing to this signed 7-bit register (see
the Phase Compensation section).
Phase B Phase Calibration Register.
Phase C Phase Calibration Register.
Active Energy Register Divider.
Reactive Energy Register Divider.
Apparent Energy Register Divider.
Active Power CF Scaling Numerator Register. The content of this register is used
in the numerator of the APCF output scaling. Bits [15:13] indicate reverse polarity
active power measurement for Phase A, Phase B, and Phase C in order, i.e., Bit 15
is Phase A, Bit 14 is Phase B, etc.
Active Power CF Scaling Denominator Register. The content of this register is
used in the denominator of the APCF output scaling.
