3The welding installation considerations, follow these steps:

1. The components are welding the front board, from low to high principles, namely the first low welding components, such as, capacitor, resistor, diode, etc.

2.Welding I C socket, terminal blocks, finally power socket, adjustable potentiometer.

3.The back with a diagonal cutting pliers to cut short the pins as far as possible

4 Debugging steps:

1After completion of welding on I C, XR2206, pay attention to the direction of I C, insert the might damage the chip!

2. check the I C whether against, such as anti please timely correction.

3. Insert the power supply, power supply for 5.5 * 2.1 port, inside outside is negative polarity. For 9-12 v power supply voltage. The waveform may not be stable for more than 12 v

5 Using the step

1. J1 jumper cap plug in, SIN/TRI blue terminals output sine wave (note J1, J2 can only insert one of)

2. J2 jumper cap plug in, SIN/TRI blue terminals output triangular wave (note J1, J2 can only insert one of)

3. SQU blue terminals output pulse

4. AMP : Sine wave, triangle wave amplitude adjustment

5. FINE : Frequency fine adjustment

6. Coarse : Frequency of coarse adjustment
