Paul,

another question. I was following your mathematical computation on how to make your own shunt and amp meter. Now here is the problem. I have made a 2/0 wire cut to exactly 1'-4" or 16". And Im also using the same cheap HF digital tester. But my reading is half of what it should. So instead of 200 amps, it was reading 400 amps. In order to correct the reading, do i need to shorten the wire half? or lengthen it twice?

Im assuming I need to lengthen the wire twice the length of what it is now.

Thank you for your help.
