摘要
介绍以单片机为核心的自动量程切换频率计的设计原理，给出了测量范围的扩展与精度的提高方法。
This paper introduces the principle of a frequency meter with automatic switching the range from 0. 1Hz to 100KHz, which is commanded by single - chip comouter. The methods about extending the measurement range and improving the precision are also given.
