Measuring Capacitance
Capacitance is the ability of a component to store an electrical
charge. The unit of capacitance is the farad (F). Most capacitors
are in the nanofarad (nF) to microfarad ( F) range.
The Meter measures capacitance by charging the capacitor with
a known current for a known period of time, measuring the
resulting voltage, and then calculating the capacitance.
To avoid possible damage to the meter or to the
equipment under test, disconnect circuit power
and discharge all high-voltage capacitors before
measuring capacitance. Use the dc voltage
function to confirm that the capacitor is
discharged.
