Facilitate use of electronic scales have been used in various industries, and has a wide range of applications. Not only has high-precision electronic balance measurement and realization of multifunctional, multipurpose. Domestic production of weighingscales manufacturers has grown to hundreds of homes, mainly in the non-automaticweighing instrument and automatic weighing instrument mainly. Electronic scales has expanded from introducing technology into their own development and design, especially for non-automatic weighing instrument of the weighing displaying controller developed by leaps and bounds. Automatically scales and scales are divided into twobroad categories of non-automatic weighing instrument, and the widespread use ofnon-automatic weighing instrument on the market. It is mainly used for trade, tradesettlement, is the most electronic scales of the masses, for example the widespreaduse of electronic platform scale. e valuation and electronic scale; automatic weighing instrument is common in industrial scale, quantitative packing scale, etc. Electronic weighing instrument is mainly composed of weighing display controller, weighing sensor and electrical control components, rational selection of weighing display controller and load cells is the key to determine the quality of the product, which determines the scale's accuracy, reliability and failure factors and other parameters. How tobuy electronic scales and weighing display controller that users are most concerned about the issue.

　　Currently on the market weighing precision grade (III) scale, display of 3000 minutes with the minimum Division value according to the weighing ranging in size from 1gto 50 kg (for example 15 kg electronic price computing scale the minimum graduation indexing value for 5G). At the time of purchase: as a case of 15 kg electronic price computing scale;

　　1, in the empty scale State and the largest weighing State figures show a steady (not blinking);

　　2, one-third maximum weighing capacity weight (or close to this value) on the weighing table 1/4 (scale divided into 4) test points within the context of digital are the same;

　　3, such as conditional maximum weighing standard weight on the scale counter to test their accuracy;

　　4, close to the maximum weighing capacity of standard weight (or close to this value weights) repeat load 3 times, testing various numbers are consistent;

　　5, press the function key, test the function keys are good contact, get it;
