FRONT PANEL GENERAL DESCRIPTION
The front panel contains the LCD, keyboard, and display contrast adjustment control.
5.2.1
LCD Screen
The LCD screen provides information to the user with 2 lines of 40 characters. Several
different sets of screen information can be displayed. A representative screen display is
shown below:

Screen displays can be menus, which permit the user to access other screens, non-
editable screens that display information only, or screens with active data fields that
can be changed by the user.
5.2.2
Display Cursor
When a screen parameter is editable, a flashing LCD cursor highlights the display
character located at the cursor position. This parameter is changeable by the user.
5.2.3
Display Contrast Adjustment
Pressing the
Contrast
button, located to the left of the LCD screen, allows the user to
optimize the contrast and viewing angle of the displayed text. It may be necessary to
depress the button for several seconds in order to notice any changes. Releasing the
button for a couple of seconds and then depressing it again causes the adjustment
direction of the viewing angle to reverse. Repetitive pressing of the button moves the
viewing angle in the same direction. The last setting is retained in non-volatile memory,
and only needs to be changed when gross changes in ambient temperature occur.
