Instrument Controls
The instrument front panel provides these user
interfaces:
• A touch screen acting as display, touch
pad and keyboard. Contrast can be
adjusted.
• A LED, showing when the instrument is
on.
• A buzzer sounds each time the screen is
touched, and when an event alarm is set.
Sound level and type can be adjusted.
Touch Screen
The user interface on the front panel is a 320x240
pixels display with touch-screen. To make
navigation user friendly, the interface software is
Windows CE based, providing easy selection
through menus.
All the measurement, configuration, calibration
and "standard service" routines can be called by
pressing buttons and menu bars on screen.
Measurement display shows one measurement
slope.
Display can be configured to only show a single
sensor measurement, or to show a parametrable
graphic representation of the last measurements.
Touching some items on the display calls a
related function.
Menu navigation
Pressing the “menu” button in the header bar calls
the main menu. The display is made of three
columns:
• Left column is the menus, or submenus
(greyed out options are not available)
• Center column shows a tree view of
actual position inside menu structure
• Right column has the following generic
controls
• Up - Return to a previous menu
• Main - Jump directly to the main menu
• Close - Close the menu and return to
the measurement view display
• Help - Help topics relating to the
current menu
Virtual Keyboard
When a text box (alphanumeric field) has to be
edited and is pressed, a virtual keyboard appears
on screen. It can be used as a PC keyboard
(pressing CAP give access to special keys).
Once values have been entered, press the Enter
key to confirm and exit the virtual keyboard.
