Make sure to take some safety precautions when you are working around capacitors or you need to discharge them. You will need to have insulated electric screwdrivers, safety gloves and electrical safety glasses. Electric Insulated screwdrivers and pliers
For safety capacitors above 0.01 μF, the R × 10k range of the multimeter can be used to directly test the capacitor for the charging process and internal short circuit or leakage. The capacity of the capacitor can be estimated according to the amplitude of the pointer swinging to the right during the test.
To test a capacitor with resistance, you need to follow these steps: Disconnect the capacitor from the circuit. As before, you need to make sure that the capacitor is not connected to any power source or other components in the circuit. Discharge the capacitor.
To prevent a capacitor from failing, you should not exceed its rating. If the voltage applied is lower than the rated voltage, then you don't have to worry. However, a higher voltage rating increases the price. In your case, a 440 VAC V A C capacitor will do just fine. Alternatively, a 250 VAC V A C capacitor would also suffice at a lower price.
Instead of these tests, critical operating conditions which could lead to the failure of a PEC capacitor (voltage/current/tem- perature) should be monitored within the application. 8.
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.
