Adjust RF on Collision Cell in Agilent 7000QQQ

[James_Ball]

Running through the self diagnostic program and this is just above the acceptable limits and wondering how you DIP the Collision Cell RF. Done it many times on the main quads, but don't see any apparent adjustment screws on the collision cell board.

You can't adjust cell RF separately, because in most cases cell RF derived from quadrupole.

Actually I am wanting to adjust the coils for it since the RF reflected voltage is too high. I think I found the adjustment just wondering if anyone else had any experience with it.
