 About power and reactive power full scale range selection
The power range and reactive power range is automatically decided in a current range and voltage range.
The full scale range of a bar graph can be selected out of the following values within a 40 to 115％ (range of active
power) and 30 to 115％ (range of reactive power), assuming that the rated power (VT ratio × CT ratio (
1.0 / 1.2 / 1.4 / 1.5 / 1.6 / 1.8 / 2.0 / 2.4 / 2.5 / 2.8 / 3.0 / 3.2 / 3.6 / 4.0 / 4.2 / 4.5 / 4.8 / 5.0 / 5.6 / 6.0 / 6.4 / 7.2 /
7.5 / 8.0 / 8.4 / 9.0 / 9.6 ×10
Example) In case of VT ratio × CT ratio ＝ 1200kW
A full scale range can be selected from the following.
480 / 500 / 560 / 600 / 640 / 720 / 750 / 800 / 840 / 900 / 960 / 1000 / 1200
Note ( 23 ) Assume VT ratio is "2" for calculation in case of 220V input specifications and also assume CT ratio
is CT ratio ÷ 5 in case of 1A input specifications.

：Average value within instantaneous measurement or the demand time limit. (One is
selected by setting.) Calculates for active power and reactive power.
：Zero cross cycle computing type.
