Capacitance meter
open-in-new
<p>A capacitance meter is a piece of <a href="/facts/Electronic_test_equipment/0z8CCX04">electronic test equipment</a> used to measure <a href="/facts/Capacitance/0pH046TL">capacitance</a>, mainly of discrete <a href="/facts/Capacitor/hyowqv7n">capacitors</a>. Depending on the sophistication of the meter, it may display the <a href="/facts/Capacitance/0pH046TL">capacitance</a> only, or it may also measure a number of other parameters such as <a href="/facts/Leakage_(electronics)/Nd6PNxhV">leakage</a>, <a href="/facts/Equivalent_series_resistance/aFdLgDVV">equivalent series resistance</a> (ESR), and <a href="/facts/Inductance/oIxj7JxX">inductance</a>. For most purposes and in most cases the capacitor must be disconnected from <a href="/facts/Electronic_circuit/IRfQ6Cc2">circuit</a>; ESR can usually be measured in circuit. </p>
