Frequency Counter 6 Digits

Features

• 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 is 0.1 seconds, real-time display of frequency.
• The precision of frequency measurement 10Hz/100Hz (Rotated 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.
