One of the most common ways to test a capacitor is by using a multimeter. We can do this test in two different ways: Using a multimeter to test a capacitor is straightforward: Set your multimeter to the capacitance (usually labeled as “C”) mode. Discharge the capacitor by short-circuiting its terminals with a resistor or insulated screwdriver.
Testing a capacitor with a multimeter is a straightforward process that allows you to determine if the capacitor is functioning correctly. Here’s a step-by-step guide on how to perform this test: Set the Multimeter to Capacitance Mode: Turn on your multimeter and select the capacitance (C) mode.
1. How to test a capacitor without capacitance measurement If only a simple multimeter without a function for capacitance measurement is available, then only the rough functionality of the capacitor or electrolytic capacitor (electrolytic capacitor) can be checked.
Set the multimeter in continuity mode. Place the multimeter’s red probe on Anode and black (common) probe on Cathode of the capacitor. If the multimeter show sign of continuity (beep or LED) and then it stops (shows OL). It means the capacitor is good.
For a good Capacitor, every attempt of the test should show a similar result on the display. If in the further tests there is no change in the resistance, then the capacitor should be replaced as it is a dead one. At first, the Capacitor must be disconnected from the circuit board and then it should be discharged completely.
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.
