REAL-TIME READINGS
The power meter measures currents and voltages and reports rms values
for all three phases and a calculated neutral current
➀
. In addition, the power
meter calculates true power factor, real power, reactive power, and more.
Table 8-1 lists the real-time readings and their reportable ranges.
➀ PM-620 and PM-650.
