Ifr you are not using that inlet then set the flow and pressure to zero and plug the column connection with a nut and blank ferrule.

Have you checked setup of instr? in column section, have you left original column configured? For example 30m *.025?
sometimes 3800 gc require fake configuration on inlet, even if you don't install col: so enter setup, and insert 1m*0.25 in conf and reboot
Sometimes with my 3800 has worked

Thnks for replay
I have done that
Now change of topic
In other unit of varian 3800 GC i am unable to make injection beacuse Gc is nit geting ready due to flow not geting stabilised by EFC. I checked al connection for leakages,The Septa changed,Capillary column leakage cheked
The Pressure is 10 PSI and I get set pressure 10 psi and actual pressure is 45 PSI ? What is the problem?
