The circuit monitor measures currents and voltages and reports in real time
the rms values for all three phases, neutral, and ground current. In addition,
the circuit monitor calculates power factor, real power, reactive power,
and more.
Ta bl e 4 –1 lists some of the real-time readings that are updated every second
along with their reportable ranges. When you are viewing real-time readings
from the remote display or
SMS, the circuit monitor is displaying 100-ms
readings.
