mitutoyo 501s Manuel D’Utilisation

 

For measuring segment 1, as in the case of measuring 

the runout, be sure to arrange a reference pin or 
knife-edge at the focal point, as shown on the right. The 
inclination of the reception signal becomes large, resulting 
in degraded repeatability, unless the reference pin is 
provided.
