How To Check A Start Capacitor With A Multimeter

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.

How to check a start capacitor with a multimeter.

Hold the probes by their base without touching the metal pins on the end. Disconnect and discharge the capacitor to check a capacitor with an ohm meter you must do two things. This one covers testing of the start capacitor. Make sure the capacitor is discharged.

If you suspect the capacitor is dead conducting an ohm meter test is the easiest way to find out. Most multimeters don t have this function though but you can still test a capacitor using the voltmeter or ohm meter setting. If is used in a dc circuit set the dmm to measure dc voltage. Connect the meter leads to the capacitor terminals.

Set the meter on ohm range set it at lease 1000ohm 1k. Once both probes come into contact with the terminals on your capacitor the readout on your multimeter will start to change. If the capacitor is used in an ac circuit set the multimeter to measure ac voltage. To test a capacitor by dmm digital multimeter follow the steps given below.

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. Connect the multimeter probes to the terminals of the capacitor. Use your multimeter to confirm the capacitor is fully discharged. The reading on your multimeter will tell you if the capacitor is working properlyor needs to be replaced.

In case of non polarized capacitor connect it either way as they do not have polarity. Use your digital multimeter dmm to ensure all power to the circuit is off. Place the red probe on the positive terminal and the black probe on the negative. Take your multimeter and set it to capacitance.

If your capacitor is in working order the reading should start rising and after it reaches a certain point it should start falling because the capacitor has begun to absorb the energy from the multimeter.
