6.19 Temperature Gain Register ( TGain )

Address: 29

Default = 0x34E2E7 = 26.443169

Sets the temperature channel gain. Temperature gain (TGain) is utilized to convert from one temperature scale

to another. The Celsius scale (oC) is the default. Values are represented in unsigned notation and in the range

of 0

≤ TGain < 128, with the binary point to the right of the seventh MSB.

6.20 Temperature Offset Register ( Toff )

Address: 30

Default = 0xF3E7D0 = -0.094488

Temperature offset (Toff) is used to remove the temperature channel’s offset at the zero degree reading. Values

are represented in two's complement notation and in the range of -1.0

≤ Toff < 1.0, with the binary point to the

right of the MSB.

6.21 Apparent Power Register ( S )

Address: 31

Apparent power (S) is the product of the VRMS and IRMS. The value is represented in unsigned binary notation

and in the range of 0.0

≤ S < 1.0, with the binary point to the left of the MSB.
