*1 MPE: Maximum permissible
error J MPE
*2 Maximum permissible error of the indication measured by contacting the full measuring face with
the object to be measured. J MPE is
a term specified by JIS B 7502: 2016 which has been prepared based on ISO
3611: 2010 with some modifications of the technical
contents. The measurement method has not been changed from
JIS B 7502: 1994.
