(1) Display the positive and negative energy totalizers
(2) Upon entering this window, the circular display function will be started automatically.
The following windows will be displayed one by one, each window will stay for 8
seconds: M95>>M00>>M01>>M02>>M02>>

This is not a window but a command to print the pipe parameters.
By default, the produced data will be directed to the internal serial bus (thermal printer).
You can also direct those data to the serial communication

M98
This is not a window but a command to print the diagnostic information.
By default, the produced data will be directed to the internal serial bus (thermal printer).
You can also direct those data to the serial communication

This is not a window but a command to copy the current display window. By default, the
produced data will be directed to the internal serial bus (thermal printer). You can also
direct those data to the serial communication port.
By use of the window copying function, you can hardcopy very window displaying
manually by switching windows, or you can obtain the window displaying data by
communication.
