4.4 Selecting the Measurement Range in case of Direct Input
Power Range
The measuring range for active power, apparent power and reactive power is
determined as follows.
Wiring Method
Single-phase, two-wire (1Φ2W)
The maximum display is 99999 (when the number of displayed digits is 5).
When the result of "voltage range × current range" exceeds 1000 W (VA or var), the
unit on the display will change to "kW (kVA or kvar)".
Power range table
• A list of the combination of voltage and current ranges and the power range are
shown below. The table shows the active power range (unit: W). The range for
apparent power (unit: VA) and reactive power (unit: var) will have the same magnitude
as the active power. Read the unit as VA or var for apparent power and reactive
power, respectively.
• The following table shows the case when the number of displayed digits is four.
When the number of displayed digits is set to five, one digit is added to the lowest
digit of the values in the table. For selecting the number of displayed digits, see
section 4.12.

Note
When the range is set to auto, the measuring range switches according to range up/range
down conditions. Therefore, the range may vary even if the measured values remain the
same.
