Concentricity.

Guys i am using a hexagon global lite, and the drawing requires that the upper plane needs to be 0.02 flat, and the bores (166_H7), concentric 0.02 mm. I did my calibration and everything went perfect. making an aligment where my upper plane is set to level my Z+ axis, the axis of one of the cylinders to rotate the Y axis, and the center of the bore are used to set the origin. The other circle is off 0.086 mm. Is this way accurate. How concentrity function is calculated by pc-dmis (ISO), and does it has really a meaning (that the part will not assamble if the the tolerance is not respected? Thanks and sorry about my english.
