PHI VersaProbe 3 Notes before Acquisition Before starting acquisition: Make sure only desired positions are checked on Sample tab. Make sure only desired Regions are checked (XPS tab/ Spectrum Tab (RHS)). Make sure XPS Properties dialogue has been examined Auto Neutralizer is on/off as needed. If using queue feature and moving to multiple positions, can use Auto Z- Align. Ideally, Neutralizer and Ion Gun should warm up in standby for a little while before use. Can use Queue feature to automatically perform multiple tasks. If desired, take SXI image and Define points on image. Must push camera icon to save SXI before defining points. ** Press Add to Q and then delete all previous items in Q before pressing Start.*** 10
