4.1 List of functions

Functions of QE81WH are provided in Table 4.1-1
The "n" that is used in this and later chapters (for example: Xn0, Yn0, Un\G0, etc.) refers to the number
that appears at the beginning of QE81WH.

sequentially stores the records into a buffer memory.
The electric energy only for a period of time when a
Periodic electric certain output signal is ON will be stored in the buffer
energy memory.
Periodic energy 1 and 2 can be measured independently.
For current demand, voltage, electric power demand, and
