1. 测量方式可以随被测信号的频率变化自动进行切换，>1000Hz时，定时计数方式；<900Hz时，测周期,切换点可以随时自定义，可以做到最佳的匹配。
2. 可以通过改变晶振或者单片机来提高测量范围，有四个常用晶振的宏选择
3. 精度高，通过软件修正、再配合高频晶振以及更换单周期指令的单片机，高频时，可以做到+-2Hz的误差。-1. A measurement with the measured signal frequency changes automatically switch,> 1000Hz, the timer count the ways <900Hz, the measurement cycle, the switching point can be custom
You can be the best match.
2. Can change the crystal or single-chip to improve the measurement range, there are four commonly used crystal macro select
3. High precision, coupled with the high-frequency crystal oscillator and the replacement of single-cycle instruction microcontroller software correction, the high frequencies, can be done+- 2Hz error....
