Description: strong! Table homemade capacitance of the source and PCB plans, many chip capacitors are not marked with capacitance values, and I could not bear to throw them; Circuit done playing, I always see some circuit board waste a lot of chip capacitors, used to be removed, but I fail to see the capacity, very depressed. So I decided to make a capacitance meter to test their capacity. I used SCM 8952 and voltage comparator 339 to do a simple capacitance measurement table, along the following parameters : capacitance measurement range to max-9999.99uF, minimum resolution of the disturbance. Divided into five range, it will automatically switch range can also manually switch. In addition, a simple function of frequency meter, capable of measuring 0-60MHz digital signal frequency (TTL level); Some ca
