Default = 0.0125 (4.0 kHz x 0.0125 or 50 Hz)
Epsilon is the ratio of the input line frequency to the output word rate (OWR). It can either be written by the ap-
plication program or calculated automatically from the line frequency (from the voltage input) using the AFC bit
in the Modes register. 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.

Default = 1 (250 uS at OWR = 4 kHz)
PulseWidth sets the duration of energy pulses. 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 8,388,607.
Default= -1
PulseRate sets the full-scale frequency for E1, E2, E3 pulse outputs. For a 4 kHz sample rate, the maximum
pulse rate is 2 kHz. This is a two's complement value in the range of -1 ≤ value < 1, with the binary point to the
left of the MSB.

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.
Address: 20 ( Q1
Wideband reactive power is calculated using vector subtraction. (See
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.
