Hello, I have a vernier caliper like:and tried to measure small AWG wire size. I do not have in hand any small wire that I know the size to compare. I do need to measure the precise size of the wire I have. Now, the problem is that when I put some pressure with the vernier, the reading can change from 30 AWG to 34AWG, which make a huge diffence in my calculations... And I also have to take into account the insulation and taking out! I do not have a wire gauge.
Should I put the pressure or not?
