5. Display and Key-press Operation
5.1 Display Instruction
In energy data displaying interface, the LCD displays KWH value in 6 +1 digits (999999.9 KWh).
In parameter setting interface, the menu setting options are in order of : CT ratio programming, communication
address programming, baud rate programming, clear energy.
5.2 LED Lights Instruction
On the panel of the meter, there are 3 LED lights in order of
(COM), (PULSE), (REV).
(COM)
is communication indicating light. When the communication is normal, the light flashes once every two
seconds. When communication error, the light flashes twice a second. In case communication blackout, the light is
off.
