Customer ServiceThe capacitor may need to have one leg removed. Safety Note: Larger capacitors in particular hold their charge even in the event of a power outage. Always discharge capacitors before handling them or testing them to
Customer ServiceOnce the capacitor has been discharged, you can begin to test it with an ohmmeter. Before doing so, however, you should make sure that there are no obstructions on or near the terminals of the capacitor. This is important because any obstruction can interfere with the testing process and lead to inaccurate results. Test the capacitor
Customer ServiceWhen you test a cable, the wires behave like a capacitor. This capacitance becomes especially important during a hipot test when high voltage is applied between two wires. The higher the voltage and capacitance the
Customer ServiceFor example, you might have a machine which runs clockwise and then anti-clockwise and this is the reason why this type of capacitor motor is used. The 2.5uf capacitor is strapped across the two ''input'' wires, although as I have mentioned above, only one of these ''input'' wires are actually connected to the electrical supply.
Customer Service(4) Before working on the capacitor, a test discharge must be carried out. This kind of discharge is to place the discharge rod on the lead terminal of the capacitor for a period of time. (5) Even if both sides of the capacitor device are grounded, in order to prevent the residual charge on the capacitor, a test discharge must be performed.
Customer ServiceElectrolytic capacitors have a habit of failing over time, check for domed heads, or if they are raised from the PCB surface have a look between their legs to see if the sealing cap has pushed out - sure sign of a failed cap. Cable interconnects are also a weakness, make sure they''re all pushed home fully.
Customer ServiceTherefore, you can expect the current will always be flowing in the capacitor. When you test a cable, the wires behave like a capacitor. This capacitance becomes especially important during a hipot test when high
Customer ServiceMost digital multimeters come with an inherent mode to test the value of a capacitor, as shown in Figure 2 (note the symbol of capacitor). This is the most common method for testing a capacitor. A capacitor can be tested for its functionality directly by entering the capacitance mode in the multimeter and performing the following steps:

Customer Service1. Expose the capacitor. Here, too, the first thing to do is to completely remove the capacitor to be checked from the circuit. All contacts to the circuit must be removed and the two poles of the capacitor made freely accessible.
Customer ServiceTo test a capacitor with a multimeter, follow these steps: Set your multimeter to the capacitance mode, discharge the capacitor, and connect the probes to the capacitor terminals with the correct polarity.
To test a capacitor, follow these steps: On the display of the digital multimeter, a measured value should now be shown for a fraction of a second that you have to remember. The measurement display will then immediately jump to OL (Open Line). Repeat this process twice for a complete test.
You have a capacitance meter or multimeter with a capacitance feature and by using it you can verify the capacitance value of a capacitor. And sometimes you can use the same meter to identify a bad cap if the capacitance value is not in the tolerance range of the manufacture provided data. i.e.
When the capacitor is outside the board, sometimes a bad capacitor may give you a proper capacitance value on the multimeter or capacitor meter. No doubt, multimeter, or capacitor meters are used to measure capacitance. They just cannot be trusted to tell you if the capacitor is bad or good, whether it is outside or inside the circuit board.
To check if a capacitor is bad, first inspect its voltage rating, which should be printed on the outside. If the capacitor is leaking, bulging, or has a short circuit, it is likely faulty. Additionally, you can use a multimeter to test its capacitance and leakage current.
Before connecting the test leads to the capacitor terminals, keep test leads connected for a few seconds to allow the multimeter to automatically select the proper range. To place a multimeter in Relative mode for capacitance, leave the test leads open and press the REL button. This removes the residual capacitance value of the test leads.
