If the red port is a low amp (200 mA) but it has a 10 a port why does it cause damage to the multimeter to use the 10 A port?
In: Technology
The 10A means it can measure amperage *up to* 10A. But the meter will allow more than 10A to flow through it: so, hooking it up straight to the battery allows the battery to send *all* of it’s amperage through the meter. Hopefully this just blows the fuse, but the meter might also melt/burn before the fuse can blow.
This doesn’t happen in voltage mode because then the meter allows only a tiny trickle of amperage to flow through it.
