Setting the flow volume (19" rack)
On systems with 19" rack with integrated pneumatics, it is possible to set the reference or
test air volume on the electronics. A distinction is made here between the pump and
instrument air version:
●
Only the test air volume can be set for the pump version.
●
With an instrument air version, it is possible to set both the reference and test air
volume.
