Real-Time Readings
The power meter measures currents and voltages, and reports in real time the rms values
for all three phases and neutral. In addition, the power meter calculates power factor, real
power, reactive power, and more.
Table 4–1 lists some of the real-time readings that are updated every second along with
their reportable ranges.
