To get your readings right on an electrolytic capacitor, connect the red probe to the positive terminal, then the black to the negative terminal.
You may have both your capacitor and voltage rating printed on the exterior your capacitor, so the next thing to do is to take note of these ratings. To carry out this test, you would have to detach the capacitor from the circuit board and completely discharge it you can do this by connecting it to a LED or powerful resistor.
If you have a digital multimeter that functions with capacitance settings, then feel lucky! It is the quick and accurate way of carrying out this test.Ĭapacitance is measured in Farads, using a multimeter with capacitance settings, it can measure capacitors as small as a few nanoFarads to bigger microfarad capacitors.
How to Test the Capacitor Using a Multimeter with Capacitance Setting You should know that the multimeter functions as a troubleshooting device that measures resistance, current, and voltage.īut the question would be “ how do you test a capacitor with a multimeter?” We would answer this question by briefly explaining how you can use multimeters with different functions to test your capacitor. To test your capacitor, you would have to make use of a multimeter (if you don’t have a multimeter check on and pick one). So apparently, one of the faults of your electronics could be with your capacitor. Capacitors are too important to ignore they are electrical components that perform significant roles in your electronics.Ĭapacitors carry out the functions of charging and discharging, which is releasing charge into the circuit through a plate of the capacitor when a first charged plate can longer hold current built up in it.Ĭapacitors are parts of the motors of your air conditioners, heaters, and your refrigerator compressors. Energy is stored in capacitors in the form of electric charges.
