The Mass Differences page in Database Manager allows you to select any peak and see the mass differences to the right and left (possible parent-daughter ions). The m/z scale can be moved using the track bar at the top of the page. If molecular mass info is available, the zero value of the m/z scale automatically starts at the molecular mass, i.e. a standard neutral loss spectrum is displayed. In this case a blue selection bar in the track bar marks the shift of the m/z scale with respect to molecular mass. The graphic can be enlarged to allow you to see the number for less prominent peaks when there are a large number of peaks close to each other.
