Description

DIY Oscillator Frequency Counter Meter Tester Kit
Feature:
This is a PIC microcontroller based on the frequency meter, with a crystal measurement function and programmable addition and subtraction frequency settings, five digital display, easy and intuitive, all use of in-line components, the circuit is simple and easy to produce.
Circuit characteristics:
Measurable frequency range 1 Hz -50 MHz
Can measure the oscillation frequency of most commonly used crystal;
Five precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz);
Automatic range conversion, without human switching;
Programmable addition and subtraction frequency settings for the measurement of radio transceivers and other equipment;
You can select the power saving mode, if the frequency is not obvious changes within 15 seconds automatically turn off the display;
You can use the universal USB 5V interface power supply, can also use an external DC power supply or 9V battery.
The number of components is small, all straight-line components, installation and commissioning simple.
