and Harmonic Display, etc.)
Note
●Accuracy is defined to rated current. Although the maximum scale may display
120% or more of
rated current and rated voltage in order to make a scale easy to read depending on the settings of
VT/direct voltage and CT primary current, current input is within 100% of rated current.
●Even if a display pattern is selected that cannot display active power, reactive power, active energy,
and reactive energy, it is possible to display the sign according to 2 quadrant / 4 quadrant
measurement of the power factor and reactive power
due to

It is suitable for the counting of equipment without the private
electric generator and the reactive power of the capacitor load at
the power factor = 0, generally.
