8.1 The Data Display Screen
When the DF-310E Process Oxygen Analyzer is powered up, it goes through a series of internal
diagnostic tests which take about five seconds. After the tests, the Servomex logo appears for
ten seconds. The display will then show the Data Display Screen as shown in Figure 32.

Figure 32: Data Display and Keypad
The numerical information shown is representative. Different values will probably be observed
on the display.
There are four pressure sensitive keys below the display. The keys are used as follows:
ESC - Returns the display to the previous screen, or may be used to move to the left
when within a data field selection.
- Scrolls up in a menu or data selection.
- Scrolls down in a menu or data selection.
- Accepts the selected (asterisk) entry, allows data field selection, and may be used
to move to the right when within a data field selection.
The Annunciator Line provides information about the status of the Analyzer, and alarm
conditions. The Annunciator Line is displayed on the Main Menu Screen.
The Data Line indicates the measured oxygen concentration (e.g. 3.43 ppm). In this manual all
concentrations will be shown in ppm O
2
. For instruments that display data in percent (%) O
2
all
actions are identical, but engineering units will be reported in percent (%).
