Description: 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
