Description

technical field [0001] The invention relates to a detector, in particular to an RC detector based on a single-chip microcomputer. Background technique [0002] With the rapid development of microelectronics technology, computer technology and software technology, electronic measurement technology is also developing, and it can even be said to be a leap, a revolution. The content of electronic measurement mainly includes the measurement of electric energy, the measurement of circuit parameters and electronic components, the measurement of electrical signal characteristics, the measurement of electronic equipment performance and the measurement of characteristic curves. Resistors and capacitors are the most basic components and the most widely used components. Therefore, the measurement of their parameter values ​​has become very necessary. There are many methods for measuring resistance and capacitance. These methods are practical, but with the development of electronic tech...
