Wiring Detection: Enable wiring detection to check if the wiring of the CTs and voltage input is
correct.
Demand Calculation: Demand calculating mode can be set as sliding window, fixed window,
rolling window and thermal according to user. When using the sliding window interval method,
user selects an interval from 1 to 30 minutes, which is the period of the calculation. The de-
mand updates every 1 minute as the window slides once. Thermal demand method calculates
the demand based on a thermal response which mimics a thermal demand meter. User selects
the period for the calculation and the demand updates at the end of each period.
•
Sliding Window Demand
You select an interval from 1 to 30 minutes, which is the period of the calculation. The
demand updates every 1 minute as the window sliding once.
•
Fixed Window Demand
You select a period time from 1 to 30 minutes, which is the period of the calculation. The
demand updates once as the period time.
•
Rolling Window Demand
You select a period time from 1 to 30 minutes, which is the period of the calculation. And
you select an interval time, which is the rolling time. The period time is must the rolling
time integer times. The demand updates once as the rolling time over.
•
Thermal Demand
Thermal demand method calculates the demand based on a thermal response which
mimics the thermal demand meter. You select the period for the calculation and the de-
mands update at the end of each period.
Energy Reading: User can choose primary energy or secondary energy by pressing key or via
communication. The energy will be reset when user switch the mode of energy calculation (pri-
mary energy or second energy). And accumulate the energy again.
Reactive Energy Calculation Method: There are two ways to calculate reactive energy(pow-
er):Mode 0: real reactive energy; Mode 1: general reactive energy
