How To Test A Capacitor

In this video i show how i use a multi meter to test and check a round dual capacitor.

How do u test a capacitor. To do this test we take the ohmmeter and place the probes across the leads of the capacitor. Check the capacitors voltage rating. Set your voltmeter to read dc voltage if its capable of reading.

Take an avo meter. How to test a capacitor testing a capacitor with a voltmeter disconnect the capacitor from its circuit. Test a capacitor by analog multimeter make sure the suspected capacitor is fully discharged.

Charge the capacitor with a known voltage less than but close to its rated voltage. Richard lloyd 2421925 views. That spark by the way tells you the capacitor probably isnt dead.

Ac fancompressor not working how to test repair broken hvac run start capacitor air condition hd duration. Connect the meter leads to the capacitor terminals. Note the reading and compare with the following results.

Touch the screwdriver to both capacitor terminals at the same time and if the capacitor is charged youll see an impressive spark. To discharge the capacitor put on a pair of rubber gloves and get a screwdriver with an insulated handle. The simple formula is start winding amps x 2652 capacitor voltage microfarads read the nameplate mfd on the capacitors and compare to your actual readings.

How to check a capacitor. Most capacitors allow for a 6 tolerance if outside of that range then replacement of the capacitor may be recommended. I use the ohm and mfd functions of the multi meter to test the capacitor.

A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting.
