4.2.3 Vacuum test with normal nozzles (calibration nozzle)
The vacuum tests in the station software for CP 20 heads check the following:
1. open / closed (Pos. B) - measurement is made from the nozzle tip to the pressure control valve.
Vacuum values = pressure control valve + holding circuit
2. holding circuit (Pos. C) - measurement is made from the nozzle tip to the holding circuit sensor.
Vacuum value = holding circuit

4.2.4 Vacuum test with closed nozzle
Closed nozzles are required in order to test the entire vacuum circuit.
C&P - CP20 / CP20a / CP20m : C&P - CP20p / CP20M2 :
„Pipette Typ 1069 / Vakuumtest C+P20“ [03094112-01] „Pipette Typ 4069/6069 kpl. / Vakuumtest“ [03106244-01]
• Switch to Setup mode.
• Choose the head functions for the appropriate gantry.
• Place all the nozzles on the placement head in the nozzle changer.
• Replace a full magazine at one of the magazine positions with one (or two) nozzle
magazine(s) containing the closed (red) nozzles.
• Pick up the closed (red) nozzles on all segments.
• Now switch to the view Manual Operations (1) => Subsystems (2).
• Choose the head functions for the appropriate gantry (3) (here gantry 4).
NOTE
Nozzle type 1069
Because nozzle type 1069 is not available for selection in the station software prior to Version
707.xx, you have to use a different nozzle type to pick up the nozzles from the nozzle changer.
Use nozzle type 2004 to do this.
Nozzle scanning must be deactivated in order to be able to pick up the nozzles from the magazine.

The error message "Vacuum distance open closed too low" must be ignored here.
