How To Check A Run Capacitor With A Multimeter

To test a capacitor by dmm digital multimeter follow the steps given below.

How to check a run capacitor with a multimeter. Set the knob on your digital multimeter to capacitance settings then connect the probes to the terminals of the capacitor. Use needle nose pliers with an insulated handle to remove wires. In case of a polarized capacitor connect the red probe with the positive terminal of the capacitor generally the longer lead and the black probe to the negative terminal. On most capacitors especially electrolytic capacitors the anode lead is longer than the cathode lead 5 check the multimeter reading.

In case of non polarized capacitor connect it either way as they do not have polarity. If is used in a dc circuit set the dmm to measure dc voltage. Connect the multimeter probes to the terminals of the capacitor. Use your multimeter to confirm the capacitor is fully discharged.

Connect the meter leads to the capacitor terminals. Connect the positive red multimeter lead to the capacitor anode lead and the negative black lead to the capacitor cathode lead. The reading on your multimeter will tell you if the capacitor is working properlyor needs to be replaced. Use a screwdriver to open your machine and locate the capacitor.

To check your capacitor you ll need a multimeter. Make sure the capacitor is discharged. Set the meter on ohm range set it at lease 1000ohm 1k. For non electrolytic you can join them either way.

How to test an appliance capacitor with a multimeter to test a capacitor to see if it is working you will first need an ohmmeter multimeter. Capacitors are metal tubes that store an electric charge usually found near a motor in the appliance. Use your digital multimeter dmm to ensure all power to the circuit is off. You will be taking a measurement reading of the electrical resistance.

To get your readings right on an electrolytic capacitor connect the red probe to the positive terminal then the black to the negative terminal. This will help to prevent shock. Make sure your device is unplugged and turned off before you find the capacitor.
