简易R、L、C测量仪是为了能够让人们比较的方便实现对电阻、电容、及电感

The simple R, L, and C measuring instruments are designed to enable people to measure resistance, capacitance, and inductance more conveniently. They are measuring instruments that meet the fast-paced life of people today. There are many advantages of simple measuring instruments such as relatively simple operation. To design a simple measuring instrument, you need to learn not only simple analog electronics and related single-chip microcomputer knowledge, but also C language programming application, which is designed by artificial thought. The design of the simple measuring instrument is various. The usual design principle is to use frequency measurement to indirectly find the corresponding resistance, capacitance, and inductance. The RC oscillation circuit and the LC capacitor three-point oscillation circuit are often used. In order to find the required frequency f, the measured frequency f can be obtained through the counting function of the single-chip microcomputer, and then the parameter value of the resistance, capacitance and inductance can be easily calculated using the known frequency f. . <br><br>Keywords: frequency, simple measuring instrument, capacitive three-point oscillation circuit
