• Adjust the pressure at the air service unit (4) (see target value on the label).
The control box and the measuring cell housing are supplied with instrument air.
• Adjust the pressure at the air service unit (3) (see target value on the label).
The measuring cell and the injector for generation of the vacuum are supplied with
instrument air.
• Adjust the vacuum with the pressure controller (6) (see target value on the label at
the vacuum pressure gauge (1)).
• Adjust a small air flow through the measuring cell with the metering valve (5).
The air flow is important for the detection of the sample backflow. The precise adjusting of
the air flow you have to do during the process step “Instrument testing” by considering
the pressure gauge (2).
