[title] How to measure high current (amp scale) | |
[* 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 jumper wire. | |
- | [* black] Connect the multimeter in-line with the circuit by touching the probes to the ends of the broken circuit. If possible, use alligator clips to hold the probes to the ends. |
+ | [* black] Connect the multimeter ***in-line*** with the circuit by touching the probes to the ends of the broken circuit. If possible, use alligator clips to hold the probes to the ends. |
[* icon_note] The polarity of the probes ''somewhat'' matters. The multimeter will measure current flowing ***into the red probe and out the black 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] Check to make sure the circuit isn't accidentally touching you or anything conductive that may short it. | |
[* black] Power on the circuit and make your measurement. |
