Value Description
0x22 IPEAK R 8 U 0
Current Peak Register. This register holds the value of the peak current
waveform that has occurred within a fixed number of half-line cycles. The
number of half-line cycles is set by the LINECYC register.
0x23 Gain R/W 8 U 0
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).
0x24 AVRMSGAIN R/W 12 S 0
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.
0x25 BVRMSGAIN R/W 12 S 0 Phase B VRMS Gain Register.
0x26 CVRMSGAIN R/W 12 S 0 Phase C VRMS Gain Register.
0x27 AIGAIN R/W 12 S 0
Phase A Current Gain Register. This register is not recommended to be
used and it should be kept at 0, its default value.
0x28 BIGAIN R/W 12 S 0
Phase B Current Gain Register. This register is not recommended to be
used and it should be kept at 0, its default value.
0x29 CIGAIN R/W 12 S 0
Phase C Current Gain Register. This register is not recommended to be
used and it should be kept at 0, its default value.
0x2A AWG R/W 12 S 0
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.
0x2B BWG R/W 12 S 0 Phase B Watt Gain Register.
0x2C CWG R/W 12 S 0 Phase C Watt Gain Register.
0x2D AVARG R/W 12 S 0
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.
0x2E BVARG R/W 12 S 0 Phase B VAR Gain Register.
0x2F CVARG R/W 12 S 0 Phase C VAR Gain Register.
0x30 AVAG R/W 12 S 0
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.
0x31 BVAG R/W 12 S 0 Phase B VA Gain Register.
0x32 CVAG R/W 12 S 0 Phase C VA Gain Register.
