Measurement Conditions
• Power Range
The measurement ranges (power ranges) of active power (P), apparent power (S),
and reactive power (Q) are as follows:
Wiring System Power Range
1P2W (single-phase, two-wire) voltage range × current range
1P3W (single-phase, three-wire) voltage range × current range × 2
3P3W (three-phase, three-wire) (when the voltage and current ranges on the corresponding
elements are set to the same range)
3P3W (3V3A, three-voltage, three-current)
3P4W (three-phase, four-wire) voltage range × current range × 3
(when the voltage and current ranges on the corresponding
elements are set to the same range)
• When the result of the equation voltage range × current range exceeds 1000 W
(VA or var), the displayed unit changes to kW (kVA or kvar).
• The display resolution is 600000.
Note
Because the voltage and current ranges switch independently according to range increase
and decrease conditions in auto range mode, different power ranges may be set for the same
power value.
