Default = 4000
Determines the number of output word rate (OWR) samples to use in calculating low-rate results. Cycle Count
( N ) is an integer in the range of 10 to 8,388,607. Values less than 10 should not be used.

Default = 1.02 (minimum difference = 2%)
Sets the hysteresis level for energy channel selection. If the most positive value of P1 AVG and P2 AVG ( I1 RMS
and I2 RMS ) is greater than Ichan LEVEL multiplied by the least-positive value, and is also greater than
Ichan MIN , the channel associated with the most-positive value will be used. If not, the previous channel
selection will remain . Ichan LEVEL is an unsigned fixed-point value in the range of 0 ? value ? 2.0, with the bi-
nary point to the left of the MSB. A value of 1.0 or less indicates no hysteresis will be used .

Default = 0.003
Sets the minimum level for energy channel selection. If the most positive value of P1 AVG and P2 AVG ( I1 RMS and
I2 RMS ) is less than Ichan MIN then the previous channel selection will remain in use. It is a two's complement
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.

Wideband reactive power is calculated using vector subtraction. (See Section 4.8 Power and Energy Results
on page 16). The value is signed, but has a range of 0 ? value ? 1.0. The binary point is to the right of the MSB.
