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:
•
Dialogs with immediate settings provide a Close button but no OK button. Example: Step Size
dialog.
•
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 System – Undo! .
On-Screen Keyboard
A keyboard symbol next to a character input field opens the analyzer's on-screen keyboard.
The on-screen keyboard contains two sets of characters plus the following additional controls:
•
Shift changes between the two character sets containing lower case letters/numbers and upper
case letters/special characters, respectively.
•
<= BS deletes the current string in the alphanumeric input field.
•
OK applies the current selection and closes the keyboard. The current string is written into the
input field of the calling dialog. See also Immediate vs. Confirmed Settings .
