Peak current1 (I1_PEAK) contains the value of the instantaneous current 1 sample with the greatest magnitude
detected during the last low-rate interval.
This 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.

Apparent power 1 (S1) is the product of V1_RMS and I1_RMS or SQRT(P1_AVG² + Q1_AVG²).
This is an unsigned value in the range of 0 value 1.0, with the binary point to the right of the MSB.

Power factor 1 (PF1) is calculated by dividing active power 1 (P1_AVG) by apparent power 1 (S1).
The sign is determined by the active power (P1_AVG) sign.
This 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.
