Final Answer:

To test a capacitor using a rotary dial multimeter, set the dial to the "Resistance" or "Ohms" setting. Capacitors should be discharged before testing to avoid electrical shock.

Explanation:

When testing a capacitor with a multimeter, you typically use the "Resistance" or "Ohms" setting, which measures the resistance of the component. This is an indirect method for checking capacitors. Here's how to do it:

Safety Precaution: Ensure that the capacitor is fully discharged to avoid any electrical shock. You can discharge it by short-circuiting its terminals with a resistor or a screwdriver with an insulated handle.

Select the Setting: Set your multimeter's rotary dial to the "Resistance" or "Ohms" setting.

Attach the Leads: Connect the multimeter's leads to the capacitor's terminals. Pay attention to the polarity; capacitors may need to be connected with the correct polarity.

Reading: The multimeter should initially show a low resistance reading, which gradually increases. If the resistance steadily increases and then levels off, the capacitor is likely good. If the resistance remains very low or doesn't change, the capacitor may be faulty.

Remember that this method is not the most accurate way to test a capacitor, and it's generally used for a quick check. More comprehensive testing methods, such as using a dedicated capacitor tester, can provide more precise results.
