The History pane contains a history preview area and a history logs area. All changes made to the instrument state that originate from the Tune application are logged in this pane. A change record is automatically created each time you modify a parameter in the Ion Source pane or the Define Scan pane. The record is created after you apply and save the changes. The change record is displayed as a sub-item under the date when it was created and has a maximum limit of 100 change records.

NOTE

A change record is inactive if the source type of the change record differs from the current source type.

The following figure displays an example of the History pane.
