Set the multimeter to measure capacitance. Most digital multimeters use a symbol similar to –|(– to signify capacitance. Move the dial to that symbol. If several symbols share that spot on the dial, you may need to press a button to cycle between them until the capacitance symbol appears on the screen. If your tool has several capacitor settings, choose …

Consider Operating Temperature in Selecting Capacitors. Environment factors are also needed to consider on how to select capacitors. If your product will be exposed to an environment temperature of 100''C, then do not use a capacitor that is only rated at 85''C. Likewise, if the minimum environment temperature is -30''C, then do not use a ...
In the measurements, the frequency is classified into a higher range and a lower range. The proper conditions are applied to each frequency. Table 1 shows the measurement conditions for a temperature compensating type capacitor, and Table 2 shows the measurement conditions for a high dielectric constant type capacitor.
