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 system) Voltage range × current range
1P3W (single-phase, three-wire system) Voltage range × current range × 2
3P3W (three-phase, three-wire system)
(when the voltage and current ranges on the
elements in the wiring unit are set to the same range)
3P3W (3V3A; three-voltage, three-current method)
3P4W (three-phase, four-wire system) Voltage range × current range × 3
(when the voltage and current ranges on the
elements in the wiring unit 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 60000.
Note
In auto range mode, because the voltage and current ranges switch independently according to
range increase and decrease conditions, different power ranges may be set for the same power
value.
