Arithmetic method
Demand current measurement
Demand active power measurement：Arithmetic method according with bimetallic type (Default value).
100％ indication time is about 3 times the time delay at the case of the arithmetic method according with
bimetallic type.(In case of 10 minutes/95％ of time interval, time to reach to 100％ is about 30 minutes.)
Demand measurement is measured to the 2 times of the rated current, and the 2 times of a rated active power.
