2.5. Detecting and setting the external MFC
CIA 8 contains a MFC which is external to UNITY 2. Once the CIA 8 is correctly configured (see
above) go to ‘View – Options – Flow Control’
Click ‘Scan for Flow Controllers’ (password is Davinci) to automatically detect all MFCs
present.
Designate the external MFC to control the ‘UNITY Split & Trap’ flow by using the drop down
dialogue box.
Enter the maximum flow of the MFC into the ‘Full range ml/min’ box.
Ensure the Split and desorb needle valves on the UNITY 2 are open enough to allow the
desired flow.
