6. Instantaneous value measurement
Set the Function switch to W range.
During Inst. value measurement, if the Function switch is set to a position
other than
W , it results in the following;
Wh range : No effect
DEMAND range : No effect
SET UP range : Change/ Confirm the settings
(see “Section 4: Settings”)
Ɣ Indications
Measurement/Calculation parameter Unit

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.
