智能电子秤主要由电源、称重传感器、A/D转换器、单片机、键盘/开关、LCD显示器等部分组成。主要技术指标为：称量范围0～15kg；分度值为0.005kg；精度等级Ⅲ级。仪器主要功能有自检、去皮、计价、单价设定、过载报警等。仪器若不进行称量操作，5分钟后自动进入休眠模式，降低电源消耗。
The intelligent electronic scale is mainly composed of power supply, weighing sensor, a / D converter, MCU, keyboard / switch, LCD display and so on. The main technical indexes are as follows: weighing range: 0-15kg; dividing value: 0.005kg; accuracy grade: grade III. The main functions of the instrument include self inspection, peeling, pricing, unit price setting, overload alarm, etc. If the instrument does not carry out weighing operation, it will automatically enter into sleep mode after 5 minutes to reduce power consumption.
