The electrostatic capacitance of ceramic capacitors is generally measured using an LCR meter. 2. Measurement principle The typical measurement system of LCR meters is the "automatic balancing bridge method," such as shown in the figure below. The measurement principle is as follows.
Let’s get into the practical method of capacitance measurements. You may encounter two cases in which you may measure the capacitor. The first case would be a solo capacitor. No matter what is the situation the first step is to discharge the capacitor fully. A capacitor is a charge storing device.
A capacitor is a fundamental circuit component. It is part of almost every circuit. We use it for noise cancellation, frequency filtering, signal smoothing, and energy storage. To work with capacitors we need to learn about capacitor measurements. Because capacitor values are essential for any circuit design or repair.
Now looking at the next figure below we can clearly see that by adding an external frequency generator (IC 555 astable) to the previous circuit, it becomes possible to make the meter interpret the values of a capacitor across the indicated points, because this capacitor directly affects or is proportional to the frequency of the clock circuit.
This project shows you how to measure the capacitance of a capacitor with a microcontroller using the analog to digital converter & timer modules. The effective measurement range for the digital capacitance meter we’ll be building is from 1nF to 100uF and the resolution about 0.5nF to a few hundreds at the high end of the range.
Let’s start with our first method, the visual method. This method is the easiest and most effective way to measure the capacitance value of any given capacitor. Follow the below easy steps for an electrolytic capacitor: On the body, you will find the written capacitance value for rated maximum voltage and tolerance. It is that simple.
