The locations of these positions on a Scanning Platform sensor head package are
shown in Figure 5-15.
farWindowClearance This variable represents the distance, on the far–side
of the head package, from the measurement center
line to the edge of the largest sensor window in the
head. The window radii will range from
approximately 0.5 in. for a Smart Ash sensor to 2.5
in. for a HemiPlus sensor (see Figure 5-15).
curlDist This variable represents the additional distance that
the heads will travel when first coming on–sheet to
the prepare–to–measure position to assure that sheet
contacting sensors, such as caliper, are fully on–
sheet before making contact. The heads will then
back up to the Current Home EOS Position to start
scanning. If desired, the entire prepare-to-measure
positioning can be accomplished with the
homeHeadClearance dimension, leaving the
curlDist at its default value of 0.1 units.
positioningSafetyFactor This variable represents the additional distance that
the heads will travel when first coming on-sheet to
the prepare-to-measure position to assure that sheet
contacting sensors, such as caliper, are fully on-sheet
before making contact. The head will then back up
to the current homeScanLimit to start scanning. If
desired, the entire prepare-to-measure positioning
can be accomplished with the homeHeadClearance
dimension, leaving the curlDist at its default value
of 0.1 units.
