The Active Energy Pulse Output Accumulator (Ppulse) contains the sum of the active power and is used to drive

the pulse output. If a tamper condition is detected, this register is equal to P2Active. The value is represented in

two's complement notation and in the range of -1.0 ≤ Ppulse < 1.0, with the binary point to the right of the MSB.

The Apparent Energy Pulse Output Accumulator (Spulse) contains the apparent power and is used to drive the

pulse output. This result is updated after each computation cycle. If a tamper condition is detected, this register

is equal to S2. The value is represented in two's complement notation and in the range of -1.0 ≤ Spulse < 1.0,

with the binary point to the right of the MSB.

The Reactive Energy Pulse Output Accumulator (Qpulse) contains the sum of the reactive power and is used to

drive the pulse output. If a tamper condition is detected, this register is equal to Q2Avg. The value is represented

in two's complement notation and in the range of -1.0 ≤ Qpulse < 1.0, with the binary point to the right of the MSB.
