You need 150X minimum, 200X is much better and seems to be the standard. You also need the expertise to know what you are looking at. The stylus on your BPS is an ellipsoid, so if it is a perfect cone, you have a problem, but there is no way to tell with 30X magnification. It is really good for checking your stylus for dirt and buildup though.
Microscope for stylus inspection
What power of magnification is adequate to determine stylus wear?
I purchased a 30X hand-held scope and checked my stylus.
It looks "as-new" i.e., like a perfect cone (Sumiko Blue Point Special).
There are no obvious flats on the sides and all seems to be fine.
I could see where the technician polished the sides and left the 0 and 180 degrees points a little "rough" as they never touch the vinyl.
Does this sound O. K. or do I need a more powerful scope?
