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.
