2. Use function: The electronic scale adopts the modern weighing technology, electronic technology and computer technology integrated electronic weighing device to meet and solve the "fast, accurate, continuous, automatic" weighing requirements proposed in real life, and effectively Eliminate human error and make it more in line with the application requirements of legal metrology management and industrial production process control.

3. The electronic scale is a nationally compulsory verification measuring instrument. His qualified product is a standard with a verification index value e and a subdivision value D, and is a product protected by the national measurement method.

4. Classification of electronic scales:
1). According to the principle: electronic scale mechanical scale electromechanical combined scale 2). According to the function points: counting scale pricing scale weighing scale 3). According to the purpose: industrial scales commercial scales special scales 4). Sort by location: desktop Weighing scale refers to the electronic weighing platform scale with the full weighing below 30Kg: refers to the electronic weighing scale with the full weighing in the range of 30-300Kg: refers to the electronic weighing scale with the full weighing more than 300Kg. 4. Precision balance 5). Classification by precision: I Grade: Special balance precision ≥ 1 / 10 million II: 2. High-precision balance 1 / 1 million ≤ precision < 1 / 10 million III: 3. Medium precision balance 1 / 1000 ≤ precision < 1 / 1 million Class IV: Ordinary scale 1/100 ≤ precision <1/1000
