*** The NMR frequency needs to be controlled by hand. If you see target polarization (on the red graph) starting to drop, call the expert. They will guide you through the adjustment procedure.  This will be in the electronics room by the door to the counting room, in the third crate from the right ("CR-6"). White box which says "EIO Tube" and has a red button at the top right, which says "Move", next to a display for "Position". This will be the one to press, under guidance of the target expert.
