How to test a capacitor with a multimeter?
To test a capacitor with a multimeter, you need to follow these steps: Disconnect the capacitor from the circuit. Before testing a capacitor, you need to make sure that it is not connected to any power source or other components in the circuit. This will prevent any damage to the multimeter or the capacitor. Discharge the capacitor.
How to test a capacitor?
For a complete test of the capacitor, the measuring lines must be applied twice and the reaction of both processes must be compared: On the display of the digital multimeter, a measured value should now be shown for a fraction of a second that you have to remember. The measurement display will then immediately jump to OL (Open Line).
