and the selected measuring units.
Note: If you hold the screen too long during start up, you
get into the “service mode”. Hold the display for 6 seconds to leave the service mode.
4.10.2. Display flow reading resolution
The DB04A has the ability to show the actual flow in many different engineering units. This means
that the number of digits in the readout can change a lot. In automatic resolution mode the DB04A
calculates the required number of digits depending on the range and selected units. This resolution
is however adjustable by the user (See chapter
4.12.4 Resolution
)
4.10.3. Alarms and notifications on home screens
Flow Rate
If the flow is higher than 108% of the calibrated full scale, the message: “
Overflow
” will be
shown in the “Alarms and notification” section in the top of the screen.
If you select an engineering unit for the flow indication that has too many digits to display for
the range of the unit, the area where the flow is normally displayed, will show: “Out of
range”. Select a different flow unit in section
4.12.2 Units
Totalizer
If the totalized value exceeds the 8 available digits or you selected a totalized unit that
exceeds the current totalized flow, the totalizer will show all 9’s on it display. (9999999)
You will have to select an engineering unit for the totalizer indication that is big enough to
show all totalized flow (for instance m3n or kg). Select a different flow unit in section
4.12.2
Units
Alarm notifications
If you make use of the optional alarm module you will see the status on the main screen.
More information on the Alarm module see chapter

4.10.4. Home screens and Menu access
The
DB04A
has customer selectable “
home screens
”:
•
Overview: Shows flow + flow tot bar graph
•
Flow: Shows flow in big digits
•
Total: Shows the totalized flow in big digits
•
Alarms: Alarm screens 1 to 3 (or notification if no alarm module is connected)
** only active with alarm module
You can switch between the home screens by touching the screen for less than one second. It is
possible to hide screens with the display menu. (See compact manual
