10.5 Undoing or restoring actions
"Undo" is a function that removes the effect of the last action on the instrument and
reverts it to an older state. Conversely, "Redo" restores a previously undone action.
You can "Undo/Redo" actions according to two criteria:
●
Step by step
Gradually undo/redo the actions in reverse order as previously performed.
Depending on the available memory the "Undo/Redo" steps may restore all
actions.
●
Multiple steps at once
Select any specific action in the history list to "Undo/Redo" multiple actions in a sin-
gle step.
Note: This mode requires a system restoration file on the instrument.
