; Discharge it using a resistor. IMPORTANT: To prevent shock before handling a capacitor, you should release the potentially stored electrical charge by placing a screwdriver blade across each set of terminals. For other capacitor types, polarity is not an issue. Replace your capacitors, straight away, if you come across any of these visible signs. When testing polarized capacitors, be sure to connect the multimeter probes properly (connect the capacitor positive lead to the positive probe, and the negative lead to the negative probe). Connect the test leads to the capacitor terminals. To test a capacitor with a multimeter, discharge the capacitor, set the multimeter to test for resistance then interpret the reading. If the capacitor shows any signs of bulging, then replace it. The current from the measuring device first flows into the capacitor until it is fully charged. NOAA Hurricane Forecast Maps Are Often Misinterpreted — Here's How to Read Them. Beyond just issues with the capacitor’s multimeter readings, it’s possible to observe problems with the unit visually. You just cannot test a bad capacitor inside or outside a circuit board by measuring its capacitance value with a capacitor meter or a multimeter. Method 5 Test a Capacitor using Analog Multimeter (AVO Meter) Analog Multimeters, like Digital Multimeters, can measure different quantities like Current (A), Voltage (V) and Resistance (O). Second, the range of values, a multimeter doesn’t have a suitable range for measuring every capacitor. When electrical engineers or just radio amateurs test electronic devices, they often need to test radio components soldered on PCB. If the capacitor to be discharged is large in size like if it is a motor starter capacitor handle it with care and do not short the terminals directly. A cheap multimeter can be used to test if a capacitor is burnt out. With simple multimeters you can only determine whether a capacitor has a short circuit or whether it is being charged. The discharging of the capacitor can be done by attaching the terminals of the capacitor to a 120v light bulb with low wattage. Read the measurement displayed. Another indicator of a malfunctioning capacitor is the presence of a leaking electrolyte.
