There are generally two kinds of electronic balance calibration methods, one is internal calibration, one is external calibration, the following are their detailed steps:

At present, the entire Chinese stock market is skyrocketing, in the face of reaching more than 100 times the price-earnings ratio, the ceos of listed companies said that they could not stand it, and in this high-speed bubble state, listed companies in the instrument showed a huge crisis.

The selection of electronic balances mainly considers that the weighing and sensitivity of the balance should meet the requirements of weighing, and the structure of the balance should adapt to the characteristics of the work. The principle of choosing an electronic balance is not only to ensure that the balance is not overloaded and damaged, but also to ensure that the weighing reaches the necessary relative accuracy, and to prevent the use of a balance with insufficient accuracy to weigh, so as not to meet the accuracy requirements; It is also necessary to prevent waste caused by the misuse of high accuracy scales.

The typical development of leverage in China is the invention of the scale and its wide application. A lever is mounted on a rope as a fulcrum, one end of which hangs a weight, the other end hangs a weight or a scale, you can weigh the weight of the object.

The State Bureau of Quality and Technical Supervision on July 31, 2000 (Quality and Technical Supervision Bureau quantity [2000]117) issued the "Notice on the issuance of the implementation of Weighing instruments, gas meters, water meters Manufacturing measuring instruments License Examination necessary Conditions" the full text of the [Annex 1] is as follows:

The balance made by using electromagnetic force to balance the principle of gravity is called electronic balance. As the laboratory application becomes more and more common, the accuracy and reliability of its measurement become more and more important.

The company's main products are AE series electronic Shimadzu balance, with ten years of production experience and technology accumulation, this series of Shimadzu electronic analytical balance can now account for more than 60% of the company's total sales revenue.
