5. All direct insertion components, the number of components is small, simple installation and commissioning
Precautions for soldering and mounting, please follow the steps below:
1. Components are welded to the front panel, from low to high principle, that is, the first welding low-end components, such as capacitors, resistors, diodes, etc.
2. Welding IC sockets, terminals, and finally the power socket, adjustable potentiometer
3. Behind the use of diagonal pliers to try to cut short pins
Debugging steps:
1. After completing the welding of the IC, XR2206, pay attention to the direction of the IC, the insertion may damage the chip
2. Check whether the IC is reverse, such as reverse, please correct in a timely manner
3. Insert the power supply, the power supply is 5.5 x 2.1 port, inside and outside the negative pole, the power supply voltage is 9-12V, more than 12V waveform may be unstable
Steps for use:
1. Insert J1 jumper cap, SIN/TRI blue terminal output sine wave (note that J1, J2 can only be inserted into one of the)
2. Insert J2 jumper cap, SIN/TRI blue terminal output triangle wave (note that J1, J2 can only be inserted into one)
3. SQU blue terminal outputs pulse
4. AMP: sine wave, triangle amplitude adjustment
5. FINE: frequency fine-tuning
6. Coarse: frequency coarse adjustment
