Positive Energy Only. Suppresses negative values in P1 AVG and P2 AVG . If a negative value is
calculated, zero will be stored instead.
Enables automatic line frequency measurement which sets Epsilon every time a new line fre-
quency measurement completes. Epsilon is used to control the gain of the 90 degree phase
shift integrator used in quadrature power calculations.

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.

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.

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.
