A multimeter in resistance mode can be used to check if a capacitor is faulty or not. The basic principle used is the capability of a capacitor to charge when a current flows through its leads. To check a capacitor in the resistance mode, perform the following steps: Remove the capacitor to be tested from the electric board.
Continuity mode can be used to test if a capacitor is short-circuited or has an open circuit. Steps: Set the multimeter to continuity mode. Discharge the capacitor. Place one probe on each terminal of the capacitor. If the multimeter beeps or shows continuity, the capacitor may be shorted.
In a typical polar capacitor, the longer lead is the positive terminal, and the shorter lead is the negative terminal. Rotate the selection knob of the multimeter and select the capacitance mode.
