由于采用电子秤量系统而得到了两个主要好处,即系统有显示和准确度高。任何机械系统如果不是限制在实验室的条件下,在这两方面便都值得怀疑。数字显示消除了大多数读数错误,补偿式的机械系统不足之处还很多,而电子电路却很容易设计成能在宽的温度范围内工作,从而提高了系统的准确度。因此,带数字显示的电子秤便具备了人们所期望的优点,而且还不止于此,像模—数变换、称量结果的计算和显示的控制,都可以通过微处理机处理。
Due to the electronic weighing system, two main benefits are obtained, namely the system has a high display and accuracy. Any mechanical system, if not restricted to laboratory conditions, is questionable in both respects. The digital display eliminates most of the reading errors, and there are still many drawbacks to compensating mechanical systems, whereas electronic circuits are easily designed to work over a wide temperature range, improving system accuracy. As a result, electronic scales with digital displays provide the desired benefits, and more than that, analog-to-digital conversions, calculation of weighing results, and display control can all be handled by the microprocessor.
