Description
This is a frequency meter based on PIC microcontroller, with crystal vibration measurement function and programmable frequency settings..With five-digit digital tube display, the measurement data display is intuitive and convenient..All of them use direct-plug components. The circuit is simple, easy to make, easy to install and debug..The measuring frequency range of this DIY frequency meter is 1Hz-50MHz, which can measure the oscillation frequency of most commonly used crystal oscillators..Five-bit resolution (e.g. 0.0050kHz, 4.5765MHz, 11.059MHz) supports automatic range conversion.
