How To Test A Capacitor Using Various Methods All About

If the capacitance value is within the measurement range the multimeter will display the capacitors value.

How to check a capacitor with a voltmeter. The anode has a positive voltage and the cathode has a negative voltage. Another test you can do to check if a capacitor is good or not is a voltage test. You should know that the multimeter functions as a troubleshooting device that measures resistance current and voltage.

To check a start capacitor start by turning off and unplugging your appliance. Read the measurement displayed. Check test a capacitor using analog multimeter test check a capacitor with a digital multimeter checking capacitor by multimeter in the capacitance mode check and test a capacitor by simple voltmeter traditional method to test check a capacitor find the capacitor value by measuring the value of time constant.

Then connect the multimeter leads to the capacitor terminals. Keep test leads connected for a few seconds to allow the multimeter to automatically select the proper range. Next read the capacitance value on the outside of the capacitor and set your multimeter to its capacitance setting.

There are other testing methods other than resistance that can be used. To test a capacitor using a digital multimeter with a capacitance setting start by disconnecting the capacitor from the circuit its a part of. Then use a screwdriver to open the appliance so you can locate the capacitor which is a metal tube that should be near the motor.

Connect the test leads to the capacitor terminals. Disconnect and discharge the capacitor. To test a capacitor with a multimeter discharge the capacitor set the multimeter to test for resistance then interpret the reading.

Afterall capacitors are storage devices. Most multimeters dont have this function though but you can still test a capacitor using the voltmeter or ohm meter setting. This is the most accurate method for testing the capacitor.

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find out. In the last method i have used a multimeter that has capacitance farad scale to test the capacitor. Wear work gloves and use a screwdriver with an insulated handle so you dont shock yourself.
