About Frequency Tester Frequency Meter DIY Kit 1Hz
Description: For soldering installation precautions, please follow these steps: - The components are soldered on the back side of the board (including the screen surface of a good resistor-capacitor microcontroller), from low to high, the first low soldering components such as crystals, capacitors, resistors, diodes. - Solder the microcontroller connector, then solder, triode, button, power outlet. - With diagonal pliers on the back, shorten the pin as much as possible. Debugging steps: 1. After soldering on the IC, the microcontroller PIC16F628, pay attention to the direction of the IC, the insertion may damage the chip! 2. Check if the IC is against, if correct, please correct it in time. 3. After the check, the fourth digital tube displays 0. The installation is successful! Steps for usage: 1. Before measuring the signal, please switch the J1 jumper cap. The blue terminal is IN for signal input and GND is for GND signal. The input signal amplitude cannot be higher than 30 V, otherwise the frequency meter may be damaged. 2. Before measuring the crystal, please switch the J1 jumper cap and insert a crystal of 4 to 40 meters in JP1 to measure the crystal frequency. Note: This is Unassembled DIY Sets The package includes: 1 set of x frequency meter DIY kit crystal measurement frequency measurement
