ZVT System Overview
Screen Elements
Operating Manual 1145.1084.12 – 30 35
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.
 Cancel discards the current selection and closes the keyboard. The input field of the calling dialog
is left unchanged.
The on-screen keyboard allows you to enter characters, in particular letters, without an external
keyboard; see Data Entry. To enter numbers and units, you can also use the DATA ENTRY keys on the
front panel of the instrument.
Step Size
A step symbol next to a numeric input field opens the Step Size dialog to define an increment for data
variation using the Cursor Up/Down buttons in the dialogs or the rotary knob.
 The input value for the step size takes effect immediately; see Immediate vs. Confirmed Settings.
