If you have a 400 volt supply you can test 400 volt and higher caps.

How to test electrolytic capacitors. In that electrolytics often find use in power supply circuits applied voltages can be on the order of hundreds of volts. Disconnect the capacitor from its circuit. Check the capacitors voltage rating.

Dvms can be used to test electrolytic caps if an lcr meter isnt available. Method 3 testing a capacitor by measuring the time constant first make sure that the capacitor is disconnected from the board and is properly discharged. Set the meter on ohm range set it at lease 1000ohm 1k.

Connect the meter leads to the capacitor terminals. Set your voltmeter. If you have a 600 volt power supply you can only test 600 volt and higher capacitors.

To do this test we take the ohmmeter and place the probes across the leads of the capacitor. Connect a known resistor typically a 10 kw resistor in series with the capacitor. This information should be printed on the outside.

This is useful because electrolytic capacitors should be tested at the voltage they will see in actual use. Charge the capacitor with a known voltage less than but close to its rated voltage. Method 4 testing a capacitor with a voltmeter 1.

By taking the capacitors resistance we can determine whether the capacitor is good or bad. Check a capacitor by a digital multimeter make sure the capacitor is discharged. And then immediately it will return.

A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. If you have a 200 volt power supply. Digital meter will show some numbers for a second.

It needs to be matched to the capacitors to be tested.
