Digital frequency meter 1 Hz - 50 MHz kit for self-assembly

A set of components for self-assembly of a frequency meter with a range from 1Hz to 50MHz and a function of a quartz resonator tester.
With it, it is easy to detect a malfunction of the generator, measure and adjust the frequency.
The constructor contains only parts and a board, to assemble the finished product you will need a soldering iron, solder and flux (rosin).
It will be useful for both beginners and experienced electronics engineers. - Allows you to measure the frequency of quartz resonators;
- Power saving mode (if there is no change in the frequency readings, the display turns off automatically (0 flashes)
- Automatic switching of frequency measurement ranges
- When displaying results in kHz, the decimal point flashes
- When displaying results in MHz, the dot showing the fractional part is lit
- Possibility to independently program input polarity
- Possibility to program the value to be subtracted or added to the measured value (digital scale)
