一、概述八十年代初,一些先进国家开始把微处理机应用到天平仪器上。这样,一种精度更加稳定、性能更加可靠的新型质量计量仪器——微处理机电子天平便以它的自动称量、快速高效和多功能等特点在质量计量领域崭露头角。由于微处理机的应用,不仅为提高天平仪器的计量性能提供了更为有效的手段,而且使天平仪器具有去皮重、调零、累加、个数换算、百分比计算、平均值、偏差显示、自 I. Overview In the early 1980s, some advanced countries began to apply microprocessors to balance instruments. In this way, a new type of quality measuring instrument with more stable precision and more reliable performance, the microprocessor electronic balance has emerged in the field of mass measurement due to its automatic weighing, fast and efficient multi-function. Due to the application of microprocessors, it not only provides a more effective means for improving the metrological performance of the balance instrument, but also makes the balance instrument have the functions of tare weight, zero adjustment, accumulation, number conversion, percentage calculation, average value, deviation display, from
