power measurement method
In addition to conventional calculation methods that search for reactive power
using voltage, current, and active power, you can select the reactive power
measurement method, which derives reactive power directly from voltage and
current values, just as with the reactive power volume measurement method
used in large-volume power consumers.
100Ω ±5%
For each cycle of measurement input (when a measurement item other than harmonics is set)
For every 16 cycles of measurement input (when harmonics is set as the measurement item)

the measurement of active power.
(The same measurement principle is
the same as that used to determine
reactive power by large-volume power
consumers.)
