| + | [title] Measuring low current (cont'd) |
|---|---|
| [* black] ***Power down the circuit you're measuring.*** | |
| [* black] Choose the point where you want to measure the current. You'll need to break the circuit at that point. This may mean snipping a wire, disconnecting a connector, or removing a connecting jumper wire. | |
| [* black] Insert the multimeter in-line with the circuit by touching the probes to the ends of the broken circuit. | |
| [* icon_note] The polarity of the probes ''somewhat'' matters. The multimeter will measure current flowing from the black probe, through the multimeter, and out the red probe. If you reverse the probes, it will show a negative value on the multimeter, but it won't damage the meter. | |
| [* icon_caution] Confirm that the probes are only touching what they should and nothing else. | |
| [* icon_caution] Make sure the circuit isn't accidentally touching you or anything conductive that may short it. | |
| [* black] Turn on the power to the circuit and make your measurement. |
