How To Use A Multimeter To Test A Pool Pump Motor Winding

This one covers testing of the start capacitor.

Test motor capacitor digital multimeter. How to test a motor capacitor with a multimeter. Take your multimeter and set it to capacitance. Some multimeters measure capacitance directly by supplying a voltage across a capacitor and measuring the discharge current.

Set the meter on ohm range set it at lease 1000ohm 1k. There are other testing methods other than resistance that can be used. Most multimeters dont have this function though but you can still test a capacitor using the voltmeter or ohm meter setting.

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find out. Since they are pretty big and sturdy it is unlikely that they will get physically damaged but nevertheless do it. Make sure the capacitor is discharged.

To test a capacitor with a multimeter discharge the capacitor set the multimeter to test for resistance then interpret the reading. Connect the meter leads to the capacitor terminals. To test a capacitor by dmm digital multimeter follow the steps given below.

Here i am testing a start capacitor and a run capacitor for an electric fractional horsepower single phase motor. Place the capacitor on the table or any other flat surface. Testing procedure for capacitors using a standard analog multi meter.
