　　能随时检测在称重盘上物体的重量，并显示出来。

　　根据输入的单价，计算出需要的金额。并显示出来。

　　在此基础上的物体的累加，可以直接计算第二种物体的重量，和累计金额

　　重量和价格要求精确到小数点后三位。

　　如果所有重量从称重盘中取下，系统自动复位到初始状态，等待下一次的称重。-Design content

Intelligent electronic scale hardware and software design to achieve the following functions.

Can be readily detected in the weight of objects on the weighing plate and displayed.

According to the input unit, to calculate the required amount. And displayed.

On this basis, the accumulation of objects, you can directly calculate the weight of the second object, and the cumulative amount

Weight and price is accurate to three decimal places.

If all the weight removed from the weighing tray, the system automatically reset to the initial state, waiting for the next weighing.
