Preferably, single-phase standard source is preferably 0.1 grade of single-phase standard source；
Preferably, also including Information reading unit, Information reading unit is connected with control unit, for reading the data of single phase poaer supply table storage inside；
As preferred structure, described self-service device being correspondingly arranged on start display lamp, electric energy meter wiring mechanism energising is the brightest, and power-off is i.e. gone out；
Being covered with at the terminals of electric energy meter wiring mechanism can the protective cover of opening type, described protective cover is correspondingly arranged on the sensor for detecting protective cover on off state, sensor is connected with control unit, described sensor preferably contacts/proximity switch, sensor detects when protective cover is opened, and is controlled as electric energy meter wiring mechanism power-off by control unit.
Method that electric energy meter checks is as follows to utilize said apparatus to carry out:
The terminals of electric energy meter wiring mechanism access and to be checked determines single-phase electric energy meter, controlling single-phase standard source by human-computer interaction interface through control unit to standard single-phase electric energy meter and to be checked to determine single-phase electric energy meter and carry out electric energy meter simultaneously and have good luck experiment, comparative test result knows the accuracy determining single-phase electric energy meter to be checked；
As method for optimizing, by the output of software simulated domestic electrical equipment and carry out showing and supply user to select on human-computer interaction interface；
Total output is being simulated and is being supplied simultaneously to standard single-phase electric energy meter on single-phase standard source and to be checked determining single-phase electric energy meter after selecting the combination of corresponding one or more electrical equipment by user, and the two carries out electric energy meter simultaneously and has good luck experiment.
By select different household electrical appliance can comparison electric energy meter have good luck the most accurate, the preset different load current of each household electrical appliance and power factor, human-computer interaction interface possesses and shows the power of various household electrical appliance and selected general power function, can arrange in family the quantity of different electrical equipment to select general power before user's comparison.
Regularly: selecting electrical appliance, set certain comparison time, the time then tests and is automatically stopped, the most tested table and the electricity of having good luck of standard scale；
Quantitative: to select electrical appliance, set certain comparison electricity, reach to stop tested table when setting electricity and power, the relatively electricity of having good luck of tested table is the most consistent with setting；
Having sound prompt function, every single stepping has voice message so that it is simpler, convenient to operate, safety.
During use, first, through simple operations, produced electricity in reading time limit certain time of ammeter storage inside, the electricity tentatively used user judges；If the electricity stored for table inside there is also query, then carry out electric energy meter metering method of having good luck and judge；Using the electric energy meter of Administration of Quality and Technology Supervision's calibrating as check standard, two ammeters carry out test of having good luck simultaneously, and the electricity after completing according to predetermined electricity recorded two ammeters is compared；When all accepting with upper type client, single-phase electric energy meter checking device can carry out the calibrating of various pilot project according to national metrological verification regulations.
Compared with prior art, it is contemplated that research can allow the client being ignorant of specialty understand that table meter is the most accurate, single-phase electric energy meter checking device uses and carries out having good luck the mode of comparison with the China State Bureau of Quality and Technical Supervision qualified electric energy meter of detection, by simulating the situation of actual electricity consumption, reflect the meter degree situation of tested table and standard scale the most intuitively, also add the public trust of detection.Simultaneously, by reading the parameter within table meter, the most greatly improve client to oneself monthly, the even electricity of every day and the Grasping level of load condition, explain from different angles and solve the problem that the metering of table meter is the most correct, use by single-phase electric energy meter checking device, localization solves the single-phase electric energy meter user query to electric energy meter charging, preferably serve client, serve society, improve service quality, the real fair, just and open realizing metering, improve electrical network CSAT.
