100A meter, shunt

[SentinelAeon]

I have a cheap multimeter from aliexpress but i ordered it without a shunt. I would like to measure high current and for that i need a shunt. My question is, is it possible to use a normal resistor of correct value or i need to order this exact shunt ? I added a link to the multimeter and image of how ur supposed to connect it.

You need a shunt with the same resistance and the appropriate power rating.
The resistance is likely somewhere around 1 milliohm, almost certainly under 10 milliohms.

100A through 0.001 ohms = 10W; through 10 milliohms = 100W!
