1.9 DISPLAY AND KEYPAD
The front panel has a display and keypad which is used to view information and perform specific
actions (purge, set stage, setup, and diagnostics). The display will normally be off in power save
mode. Pressing any key will display the status screen. The arrow keys are used to navigate through
the different functions and configuration parameters. Refer to Chapter 3 for details of menu items.
The front panel allows the user to do the following:
• Conduct a manual purge
• Manually bleed the tank
• Set stage
•
• Set minimum and maximum 4-20 mA values
• Set bubble rate
• Set averaging duration
• Set temperature units
•
1.10 CONFIGURING THE BUBBLER
The Bubbler can be configured through its front panel using the Set Stage and Setup sub-menus
(Chapter 3) or through a data logger. The Bubbler will retain the last input configuration whether set
through the Bubbler or the data logger. However, changes made using the Bubbler’s interface will
not be reflected in the data logger, unless it is an FTS Axiom Datalogger.
If using an FTS Axiom Datalogger, configuration can be done through the Axiom using the Bubbler
sensor extension. Configuration changes using the Bubbler’s screen will also be valid. See Chapter
4 for details.
Note that certain features, those which require a real time clock, can only be set through a data
logger. Refer to Table 1-1.

1.11 FIRMWARE UPDATES
Periodically, the Bubbler’s firmware may need to be updated. In that event, FTS will issue a
notification with instructions on how to conduct the update.

This sets the Bubbler’s date and time which is used on the time stamp of the Bubbler’s SD card. It does not affect the time
stamp of sent data or the timing of scheduled events as those are controlled by the data logger and the telemetry in use.
