4.4.8 Restoring the Previous Value
Parameter variations with the rotary knob are immediately set and therefore not reversi-
ble.
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.
Restoring values
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.
Restoring values that require confirmation
All settings that are not confirmed with the "Accept" button but require this additional
confirmation can be restored.
1. Press the ESC key.
A confirmation query is displayed.
2. Confirm with "OK" to abort the changes.
Select "Cancel" to return to the dialog. The previous selected settings are displayed.
Restoring values after an extended calculation has been started
Calculation and setting migth 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 require 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.
