Displayed parameters can be changed according to needs.

Refer to “6-3 Customizing display” in this manual.

NOTE

* Above parameters vary depending on each wiring configuration.

* If V1 is out of measuring range, other parameters may not be measured or calculated.

* The chosen units for the power factor and neutral current are arbitrary.
