4.2.7 Vacuumtests on C&P20p / C&P20m2 heads (vacuum pump)
In order to provide guidance when troubleshooting, a number of different modifications were
made to a CP20p head and vacuum tests were then carried out with type 4235 open nozzles
(calibration nozzles) and type 4069 closed (red) nozzles, and the results were compared.
For the sake of clarity, only the first 8 measurements that were taken are shown
here.
The modifications were always carried out on segment 1.
