Concentricity, how can I get a proper reading?

So, I am using a romer arm to measure concentricity of two holes. With a traditional CMM (and different software) we have found the concentricity of the holes to be 0.26mm. However, with the romer arm it shows the concentricity to be 2.9mm. If you take the acuals from the two holes and calculate the concentricity it should read like the traditional CMM???? Why is PC DMIS not giving me the correct reading? Any suggestions on how to measure this dimension with the Romer ARM?

  • Unfortunately, the call out is a true concentricity. S, I guess I will have to go to my management group and tell them that the $60,000 we spent on this equipment is not capable of a simple concentricity check Disappointed
    In a couple of the 42 million posts, there is comment about using code to make up the check. Do you know how to make this happen?
