	[title] Measuring low current
-	[* icon_note] There are two main methods of measuring current: in-line and non-contact. Multimeters often use the in-line method, where you insert the multimeter ~~into~~ the ~~circuit~~.
-	[* icon_caution] *~~When you measure current, your~~ multimeter acts like a low-resistance wire*. Be very aware of what you touch with the probes to prevent unintentional short circuits, which can damage your circuit or the multimeter.
-	[* icon_~~note~~] ~~Many multimeters will have~~ a ~~low~~ and ~~high current port, as they're protected by different fuses~~. ~~The current limits are normally printed next to the port. If the current exceeds the limit for a short period of time, it will blow the associated fuse.~~
-	[* icon_note] ~~The iFixit multimeter's~~ low ~~current port has a *600mA limit*. If you think you're measuring above that, use the~~ high current ~~measuring method first~~.
-	[* icon_~~caution~~] *~~Power down~~ the ~~circuit as you set up your measurement.* This helps reduce~~ the ~~chance of unintentionally shorting your circuit with your probes during setup~~.
+	[* icon_note] There are two main methods of measuring current: in-line and non-contact. Multimeters often use the in-line method, where you have to break the circuit and insert the multimeter in-line of the current flow.
+	[* icon_caution] *Your multimeter acts like a low-resistance wire when it's in current measurement mode*. Be very aware of what you touch with the probes to prevent unintentional short circuits, which can damage your circuit or the multimeter.
+	[* icon_caution] *Power down the circuit as you set up your measurement.* You can easily short something with your probes if you set up on a live circuit. This can damage your circuit and your multimeter.
+	[* icon_note] Many multimeters will have a low and high current port, as they're protected by different fuses. The current limits are normally printed next to the port. If the current exceeds the limit for a short period of time, it will blow the associated fuse. If that happens, [guide\|163239\|follow this guide\|new_window=true] to replace the fuse.
+	[* icon_note] The iFixit multimeter's low current port has a *600mA limit*. If you suspect the measurement will be above that, use the high current measuring method first.
	[* black] Plug the *black lead* into the *COM port. Plug the red lead* into the *right port*.
	[* red] Set the multimeter to the *mA mode*. If you're measuring AC, press the [link\|https://guide-images.cdn.ifixit.com/igi/1E4dSUMjEEFT4NJ2.full\|blue select button\|new_window=true] to switch to AC mode.
	[* orange] You can also measure in *μA mode* if you know you're measuring minute amounts of current. This changes the measurement range and gives you more accuracy at the μA range. Even if you exceed that range, it won't damage your multimeter—as long as you don't exceed the port limit (600mA).
