2.14.2.4 Inspect Entire Function of the C&P6/12’s Holding Circle Vacuum System
Throughput can be controlled correctly here based on the vacuum characteristic line, as opposed
to the C&P20 head. 2
Do the following: 2
: Remo
ve the pipettes from the placement head (to reach maximum throughput)
: Open in
SITEST the segments in collect position one after another and turn each in the star
rhythm into the holding circle.
The vacuum measurement in the holding circle shows a vacuum loss of approx. 10-30 mbar for
e
ach add
itionally opened pipette. 2

For six open pipettes the vacuum could e.g., fall from -580 mbar to -500 mbar. Because of the
discretionary combination of C&P20 and C&P6/12 heads on the same or different placement
machines (head modularity) it is not possible to state a fixed threshold for a minimally necessary
vacuum. For mixed operation with C&P20 heads the vacuum loss is generally significantly larger
than for operation with only C&P6/12 heads. 2
