3.1.6.1 Immediate vs. Confirmed Settings
In some dialogs, the settings take effect immediately so that the effect on the
measurement is observable while the dialog is still open. This is especially convenient
when a numeric value is incremented or decremented, e.g. via the rotary knob.
In most dialogs, however, it is possible to cancel an erroneous input before it takes
effect. The settings in such dialogs must be confirmed explicitly.
The two types of dialogs are easy to distinguish:
E Dialogs with immediate settings provide a Close button but no OK button.
Example: Step Size dialog.
E Dialogs with confirmed settings provide both an OK button and a Cancel button.
Example: On-screen keyboard.
You can also cancel an immediate setting using Setup – Undo.
