8.3.11 Temperature Gain (TGAIN ) – Address: 22

Default = 0x2F02C3

Refer to 6.13 Temperature Measurement on page 22 for more information.

8.3.12 Temperature Offset (TOFF ) – Address: 23

Default = 0xF3D35A

Refer to 6.13 Temperature Measurement on page 22 for more information.

8.3.13 Filter Settling Time for Conversion Startup (TSETTLE ) – Address: 25

Default = 30

Sets the number of output word rate (OWR) samples that will be used to allow filters to settle at the beginning

of Conversion and Calibration commands. This is an integer in the range of 0 to 8,388,607 samples.

8.3.14 No Load Threshold (LoadMIN ) – Address: 26

Default = 0

LoadMIN is used to set the no load threshold. When the magnitude of the EPULSE register is less than LoadMIN,

EPULSE will be zeroed. If the magnitude of the QPULSE register is less than LoadMIN, Qpulse will be zeroed.

LoadMIN is a two’s compliment value in the range of -1.0 ≤ value < 1.0, with the binary point to the right of the

MSB. Negative values are not used.

8.3.15 Voltage Fixed RMS Reference (VFRMS ) – Address 27

Default = 0.7071068 (full scale RMS)

If the application program detects that the meter has possibly been tampered with in such a manner that the

voltage input is no longer working, it may choose to use this internal RMS reference instead of the disabled

voltage input by setting the VFIX bit in the Modes register. This is a two's complement value in the range of

≤ value < 1.0, with the binary point to the right of the MSB. Negative values are not used.
