Capacitance Meter FAQ

A capacitance meter is an electronic test equipment used to measure the capacitance of a capacitor. Capacitance is typically measured in farads (F), the amount of capacitance that can store one coulomb of electric charge when charged to a potential difference of one volt. A capacitance meter is a device that measures the capacitance, as well as other related parameters such as Dissipation factor(D), Quality factor (Q), and Equivalent parallel / series resistances (Rp / Rs), etc. Keysight provides a series of LCR meters and impedance analyzers.
