[title] Measuring capacitance (large capacitors) | |
[* icon_note] The next two steps show how to measure larger electrolytic capacitors. These capacitors look like small cylinders. | |
[* icon_note] The iFixit multimeter can only measure capacitance up to ~100mF (millifarads). | |
[* black] Plug the ***black lead*** into the ***COM port***. Plug the ***red lead ***into the ***right port***. | |
[* black] Check to make sure the capacitor is discharged: | |
[* black] Set the multimeter to DC volt mode. | |
- | [* black] Carefully touch the probes to the capacitor's leads/pads. Treat the circuit as a live circuit and be careful not to touch anything else with your probes. |
+ | [* black] Carefully touch the probes to the capacitor's leads/pads. ***Treat the circuit as a live circuit*** and be careful not to touch anything else with your probes. |
[* icon_caution] ***Make sure the voltage is 10V or less.*** If it isn't, wait a minute to let the capacitor self-discharge, or [guide|2177|use a capacitor discharge tool|new_window=true] to discharge the capacitor. | |
[* icon_note] As you measure the capacitor's voltage, the multimeter may slowly charge the capacitor up. Don't measure the capacitor for too long to prevent this from happening. |
