Features:65MHz frequency to Microchip, PIC16F628A as the core.
Frequency reference with temperature compensation type voltage controlled crystal oscillator (2.5 ppm VC-TCXO).
Adopts gate control mode and the accurate time algorithm is unique.
Gate (refresh) time of 0.1 seconds, real-time display of frequency.
The precision of frequency measurement by 10Hz/100Hz (the right one) optional.
Dual frequency design, intermediate frequency value and plus / minus mode can be preset, and do not influence each other.
Display driver using the LED chip digital tube display, high brightness, less external interference.
Adopts six 0.56 inch digital tube display, automatic blanking invalid zero, eight stage adjustable brightness.
Simple circuit, reasonable structure, double button control, simple operation.
All settings are automatically saved, boot directly call.
