At that price, why not buy it?
Of course the OP said "calibrate." I come from a tradition that say

If you can't fix it, you don't own it.

We use something similar to this:

You will not be likely to get 100A through a 1mm conductor. The best
solution in this case is a current transformer with a rectifier circuit
if it is AC and an Arduino. I am busy with just such a project for my
plasma machine. Remember to put a very low ohmage resistor across the
transformer se

I used some similar tamura Hall current sensors in a project
some years ago.
I have a need to read dc current
36 volts up to 100 amps "reasonably" accurate
I am looking at Tamura L03S100D15 with Arduino
I am sure y'all have other suggestions hopefully cheaper
