This is a updated video with much better picture quality then my other test capacitor videos. To check a capacitor with an ohm meter you must do two things.

Test a capacitor with an ohmmeter of a multimeter.

How test a capacitor. Select analog meter on ohm always select the higher range of ohms. By taking the capacitors resistance we can determine whether the capacitor is good or bad. A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting.

Note the reading and compare with the following results. Its usually easy to remove a start or run capacitor you simply unhook it from its harness and disconnect the wires. Connect the meter leads to the capacitor terminals.

There left one choice we can use to test a capacitor and that is by measuring its equivalent series resistance esr. Ac fancompressor not working how to test repair broken hvac run start capacitor air condition hd duration. Richard lloyd 2421925 views.

How to test a capacitor. Method 2 checking a capacitor using multimeter without capacitance setting. I used a klein tools mm2000 and a klein tools cl1000 most fluke meters have these same settings.

The first is to remove the capacitor from the circuit. Method 4 test a capacitor with a simple voltmeter. In summary the best solution to test a capacitor without actually desoldering it is either using an esr meter or smart tweezers.

Both work the same and are fine to use. Charge the capacitor with a known voltage less than but close to its rated voltage. Check the capacitors voltage rating.

Take an avo meter. Method 1 checking a capacitor using multimeter with capacitance setting. However be careful to avoid touching the capacitor terminals.

Method 3 testing a capacitor by measuring the time constant. Test a capacitor by analog multimeter make sure the suspected capacitor is fully discharged. Set your voltmeter to read dc voltage if its capable of reading.

To do this test we take the ohmmeter and place the probes across the leads of the capacitor. How to test a capacitor testing a capacitor with a voltmeter disconnect the capacitor from its circuit.
