it does take a delicate touch when measuring , have to use the end of thumbscrew when measuring it will click on the ratchet when it starts to get tight, don’t overtighten and all you are looking for is a sliding fit as you move it over the diameter. If it’s warm it will expand the diameter a small amount
Sometimes when you get a mic it will have the slip gauge in it to check it’s exactly 50.00mm which can be adjusted if it’s a bit out
Hopefully you can see Marjons figures and see them on the mic
Top scale is mm bottom scale is 0.5mm and one full rotation is 0.5mm
So if the edge is past the 0.5mm mark and you get a reading of 58.5 + 0.25 then you get the 58.75mm
If you set it to 63.49 it should fit on the mains while 63.47 should not fit without force but very small margins
