Beschreibung
Zusammenfassung:	The utility model relates to an electric energy meter communication debugging, including CPU system circuit and rather than the power supply circuit who links to each other, the button is with keeping apart power switching circuit, keying circuit, optoelectronic isolation circuit and show interface circuit, the optoelectronic isolation circuit still be connected with a RS485 interface circuit, demonstration interface circuit still be connected with a liquid crystal display, RS485 interface circuit be connected communication with waiting the electric energy meter of being debugged. The utility model discloses can go out the electric energy meter messaging parameter by the short-term test to support multiple electric energy meter communication protocol, move reliable and stablely, can improve electric energy meter communication debugging efficiency
