Hi folks, I have a set of Mitutoyo callipers I thought were stainless, but the jaws have become slightly magnetised. It's a real problem because even if you wipe them clean before zeroing (A P.I.T.A.) there are always fine bits of swarf that bridge the gap as you close the jaws & become trapped. (The jaws must be opposite poles) I can easily make up an AC fed coil to demagnetise them but the question is will that cause a problem with whatever suplies the counting circuit. All suggestions welcome, hope you are all having a great Easter. Ian Sutherland, Down Under.
