MPU INSTANTANEOUS OUTPUT VARIABLES
The Demo Code processes CE outputs after each accumulation interval. It calculates instantaneous values
such as VRMS, IRMS, W and VA as well as accumulated values such as Wh, VARh, and VAh. Table 1-6 lists
the calculated instantaneous values.
V
rms
from element 0, 1, 2.
Irms_A
Irms_B
Irms_C
Irms_N
I
rms
from element 0, 1, 2 or neutral
Deviation from Calibration (reference) temperature.
LSB = 0.1
0
C.
Frequency of voltage selected by CE input. If the selected voltage is below
the sag threshold, Frequency=0. LSB Hz
