The zero-adjust procedure is described in the VxStart.pdf document included with the Vx Acquisition System. The Magnum_Zero_Check.pdf document contains various screen shots from the Vx Acquisition System tune section. The first screen shot shows the correct zero-adjustment. Additional screen snapshots show incorrect zero-adjustments. The document also includes a photo showing the location of the R11 potentiometer. This adjustment procedure applies to the Finnigan Magnum, ITS40, Tracker and Varian Saturn I ion traps. A similar procedure is required for Varian Saturn II and Saturn 3 ion traps.
