This
section provides a detailed description of each of the pairs of feature
measurements in the Board-Drill-Check action screen. The sequence of the
listing starts with Row #1 and ends in Row #1, with the measurement made
between a feature selected in the left-hand column (First El.) and a feature in
the right-hand column (Second Element).

When measurements are made between
drill features, they can be made between features on the same layer (when
Single is activated) or on different layers (when Cross is activated). When
measurements are made between drill features and rout features they are, of
necessity, made on different layers (drill and rout). This is assumed in the
following descriptions and will not be elaborated further.
In
all categories, the maximum distance reported is the highest value in the green
range (for an explanation see Doc.0501, Checklist Operation) of the relevant
category. It is referred to as a VIA2VIA parameter. If, for example:
The
maximum in this range is 12. This means that via that are further apart than 12
mils will not be reported.
