Parameter variations with the rotary knob are immediately set and therefore not reversible.
Normally, values cannot be restored in the case of mouse control because no explicit confirmation is required in this case and entries are automatically confirmed when the entry or selection field is exited.
In the case of front-panel control or operation from the keyboard, previous values can be restored as long as the new value is not confirmed, i.e. the entry is not completed.
► | To restore the values, press the ESC key. |
All settings that are not confirmed with the "Accept" button but require this additional confirmation can be restored.
Press the ESC key.
A confirmation query is displayed.
Confirm with "OK" to abort the changes.
Select "Cancel" to return to the dialog. The previous selected settings are displayed.
Calculation and setting might require different period of time. Many settings are made without noticeable calculation times; such operations are indicated by a "BUSY" message displayed in the status field of the header section.
A window with a progress indicates that the instrument performs an extended calculation that requires longer calculation time. The termination of such a calculation restores the previous values.
► | Press the ABORT button to terminate the calculation. |
All previous values are restored. |
