Testing a Capacitor With a Multimeter You can use a multimeter to test many things, including a capacitor''s health. To fully grasp how you can test a capacitor with a multimeter, you need to check the RC (resistive-capacitive) time constant. This is the time it takes for a capacitor to amass a voltage equal to 63% of the input voltage.
