1. Power off the circuit and remove the capacitor if possible. Measuring in-circuit often gives inaccurate results.

  2. Discharge the capacitor safely:

  3. Use a resistor (e.g., 1kΩ, 1W) across the leads.

  4. Avoid shorting large electrolytics directly — they can spark or get damaged.

  5. Set your multimeter to capacitance mode (⏀).

  6. Connect the probes to the capacitor leads. Polarity doesn't matter for film or ceramic caps; for electrolytics,          follow meter instructions.

  7. Wait a few seconds for the reading to stabilize — especially for high-value caps.

Hope this helps!

To discharge it, you can short the leads using a resistor (like 1kΩ or 10kΩ), or a screwdriver with an insulated handle if it's a small electrolytic (nothing high voltage though — not safe).

Also, for accurate readings:

• Take the capacitor out of the circuit if you can. In-circuit measurements are often wrong because of parallel components.

• Let the multimeter settle for a few seconds, especially with large caps.

• Make sure your test leads are making good contact.

• If your meter has a "zero" or "rel" mode, use that to cancel out stray capacitance from the probes.

And keep in mind, these DMM readings are just a ballpark — they won’t tell you if the cap has high ESR or leakage. For that, you'd need an ESR meter.
