*1 Eco-POWER METER is designed chiefly to manage saving energy.
It is neither intended nor can it be legally used for billing.
*2 Simple demand is the function only for AKW8111H. It supports only CT input (power measurement).
It doesn’t support pulse input.
Please use this simple demand function as your standard. The time used in this function is the time
set by Eco-POWER METER. Therefore it is different from the demand meter controlled by your
power company.
