3.2 Numeric setpoints
Numeric setpoints accept a numerical value within a specific range. The numeric setpoint
editor is a numeric input panel, with the current value shown on the number display. The
minimum, maximum, step, and default values are shown on the left of the keypad, and the
label of the setpoint being edited is displayed on the menu bar of the setpoint editor.

The navigational soft keys change the numeric key in focus, which is highlighted in orange.
There are also five functional soft-buttons in the popup window.
•
BkSpc : This key performs the backspace function, clearing the last digit or decimal
from the display.
• CLR : This key clears the field’s value from the display
• Default : This key returns the setpoint value to its default value.
• OFF : This key disables the setpoint and is visible only for setpoints that can be
disabled.
In order to activate the functions offered by these buttons, the user has to highlight the
appropriate button and press
Select .
The UP and DOWN front panel keys can also be used to increment and decrement the
setpoint by its step value. Clicking the ENTER key verifies the displayed value. If the
setpoint value is valid, it is stored as the new setpoint value and the editor is closed.

Default soft-button is brought to focus.
