6.6.73 Average Reactive Power Offset (Q1OFF , Q2OFF) – Page 16, Address 38, 45

Default = 0x00 0000

Average Reactive Power Offset (Q1OFF , Q2OFF) is added to averaged reactive power to yield Q1AVG

(Q2AVG) register results. It can be used to reduce systematic energy errors. These are two's complement val-

ues in the range of -1.0

 value 1.0, with the binary point to the right of the MSB.

6.6.74 AC Offset for Current (I1ACOFF, I2ACOFF ) – Page 16, Address 37, 44

Default = 0x00 0000

AC offset registers I1ACOFF and I2ACOFF are initialized to zero on reset. They are used to reduce systematic

errors in the RMS results. These are unsigned values in the range of 0

 value  1.0, with the binary point to

the left of the MSB.

6.6.75 Temperature Gain (TGAIN) – Page 16, Address 54

Default = 0x 06 B716

of 0.0

value256.0, with the binary point to the right of bit 16.

6.6.76 Temperature Offset (TOFF) – Page 16, Address 55

Default = 0x D5 3998

-128.0

value128.0 (°C), with the binary point to the right of bit 16.
