6.2 Page 1 Registers
6.2.1 Energy Pulse Output Width ( PulseWidth )
Address: 0
Default = 1
PulseWidth sets the duration of energy pulses (t
PW
). The actual pulse duration is the contents of PulseWidth
divided by the output word rate (OWR). PulseWidth is an integer in the range of 1 to 8388607.
6.2.2 No Load Threshold ( Load
Min
)
Address: 1
Default = 0
Load
Min
is used to set the no load threshold. When the magnitude of the P
Active
register is less than Load
Min
,
the active energy pulse output will be disabled. Load
Min
is a two's complement value in the range of
-1.0
 Load
Min
 1.0, with the binary point to the right of the MSB. Negative values are not used.
6.2.3 Temperature Gain Register ( T
Gain
)
Address: 2
Default = 0x2F03C3 = 23.5073471
Sets the temperature channel gain. Temperature gain (T
Gain
) is utilized to convert from one temperature scale
to another. The Celsius scale ( o C) is the default. Values will be within in the range of 0
 T
Gain
 128. The value
is represented in unsigned notation, with the binary point to the right of bit 7th MSB. See Section 5.8 On-chip
Temperature Sensor on page 19.
6.2.4 Temperature Offset Register ( T
Off
)
Address: 3
Default = 0xF3D35A = -0.0951126
Temperature offset (T
off
) 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
 T
off
 1.0, with the binary point to the
right of the MSB.
