How To Check A Capacitor With A Fluke Multimeter

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find.

How to check a capacitor with a fluke multimeter.

Discharge the capacitor as described in the warning above. When measuring low capacitance values the relative mode can be used to remove the capacitance of the test leads. Since capacitors store voltage the multimeter is also capable of reading volts so if the multimeter being used has a capacitance meter. Multimeters can function as a voltmeter and capacitors are rated with a maximum voltage that can be applied to them so this test would be centered on measuring the voltage rating of the capacitor.

There are other testing methods other than resistance that can be used. To place a multimeter in relative mode for capacitance leave the test leads open and press the rel button. The forward biased resistance of a good diode. The video demonstrates several ways to check a capacitor using a digital and analog multimeters and an lcr meter.

Most multimeters don t have this function though but you can still test a capacitor using the voltmeter or ohm meter setting. Some multimeters offer a relative rel mode. Some multimeters measure capacitance directly by supplying a voltage across a capacitor and measuring the discharge current. A multimeter set to the resistance mode ω can be used as an additional diode test or as mentioned previously if a multimeter does not include the diode test mode.
