Section 4 User Interface
4.1 Instrument
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 which sounds each time the screen is touched, and when an event alarm is set.
Turning instrument On and Off
The instrument portable versions have a power switch located on the back panel. There is no
power switch for the wall or panel instruments. The mains must be disconnected to turn the
instrument off. The LED indicates when the instrument is on.
Measurement window
Note: The ORBISPHERE 51x can be ordered with one to three channels.
The main (numeric) measurement window continuously displays:
• One to three sensor numeric values
• One to three measured sensor trends (for the last 1 minute to last hour)
• One to three measured sensor data alarm limits and other events
• One temperature value
4.2 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.
Touching some items on the display calls a related function, similar to a shortcut.
Figure 22 Numeric view
All the measurement, configuration, calibration and "standard
service" routines can be called by pressing buttons and menu
bars on screen.
Measurement displays show one measurement per sensor in
use (up to 3 lines for a 3 channel ORBISPHERE 51x).
The display can be configured to only show a single sensor
measurement, or to show a parameterized graphic
representation of the last measurements.
