[Me...] Posted May 3, 2019 Share Posted May 3, 2019 Hi all, I'm adding a 2nd reference sphere for calibrating small probe diameters (.3-.8mm). What size do you recommend? 8mm or 15 mm? Much thanks, Robert Link to comment https://qualityforum.zeiss.com/topic/18704-2nd-reference-sphere-size/ Share on other sites More sharing options...
[De...] Posted May 3, 2019 Share Posted May 3, 2019 Since you are intending to use it specifically for calibrating small probes I would suggest the 8mm. The 15mm may eventually prove to be too large for some probes depending on probe length / configuration of the probe and you might still end up having to buy the 8mm after all.

[Ca...] Posted May 3, 2019 Share Posted May 3, 2019 I have an 8mm for qualifying small probes, and a 30mm for everything else. Link to comment https://qualityforum.zeiss.com/topic/18704-2nd-reference-sphere-size/#findComment-105298 Share on other sites More sharing options...
[Al...] Posted May 3, 2019 Share Posted May 3, 2019 0.3mm and 0.6mm styli are the workhorses in our place. If you purchase your styli from Zeiss, you can use up to a 25mm diameter sphere with no interference. My G2 came with a 30mm sphere so I use that and an 8mm sphere for our qualification program.
