●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,
Note
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 ⑥Expanded counting , so setting
items for ⑥Expanded counting will be displayed.
Set the power factor scale.
If you have not set power factor to "Display pattern",
this display will be skipped.
-0.5 to 1 to 0.5
Set the combinations of imported / exported and lag / lead for active energy and
reactive energy you want to display, and set the measurement method for reactive
energy.

Combination I, II ⇒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.
Combination III, IV⇒It is suitable for the counting of equipment with the private electric
generator.
