Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Such as figure 1 As shown, an inspection method for an electric energy meter is used for inspecting an electric energy meter that has been initially installed, and includes the following steps:

[0048] Step 1. Set the frequency multiplication coefficient to n, and write the frequency multiplication coefficient into the metering module of the electric energy meter for measurement initialization operation. The electric energy meter performs measurement according to the set frequency multiplication coefficient. Error debugging; n is a positive integer;

[0049] Among them, when the electric energy meter measures, the calculation formula of the output energy is:

[0050] W=P×n×T

[0051] Among them, W is the output energy, P is the power, n is the multiplication coefficient, and T is the time;

[0052] The error of the conventional ele...

Abstract

The invention discloses a test method for an electric energy meter. The method comprises the steps of setting a frequency doubling coefficient as n, writing the frequency doubling coefficient into a metering module of an initially assembled electric energy meter, carrying out metering initialization, carrying out metering by the electric energy meter according to the set frequency doubling coefficient, and carrying out error debugging on the electric energy meter; setting the frequency doubling coefficient of the debugged electric energy meter as 1, carrying out the metering initialization, carrying out the metering by the electric energy meter according to the set frequency doubling coefficient, and then carrying out aged counting setting on the electric energy meter; carrying out a function test on the electric energy meter after the aged counting setting is carried out, and turning to a next step after the function test is finished; setting the frequency doubling coefficient as n, carrying out an error total test by adopting the metering method, and turning to the next step after the total test is finished; setting the frequency doubling coefficient as 1, and carrying out the metering initialization; carrying out factory setting on the electric energy meter; and carrying out a factory setting test on the factory set electric energy meter. A power is amplified through utilization of the frequency doubling coefficient, time for the electric energy meter to output fixed energy is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a method for checking electric energy meters. Background technique [0002] In the traditional manufacturing process of electric energy meters, error debugging and error verification occupy most of the time, seriously restricting the production efficiency. At present, how to improve the efficiency of energy meter error debugging and error inspection, how to shorten the product process production cycle and energy consumption are the bottleneck problems that plague many electric energy meter manufacturers. [0003] The existing error verification principle of the electric energy meter: energy (W) = power (P) × time (T); the pulse verification method is often used to detect the electric energy meter, and the error of the conventional electric energy meter is obtained by the pulse method, that is, the error in the electric energy meter When the energy is accumulated to a fixed ...
