6.4.17 Device Information
In the Device Information menu, the transmitter's physical configuration and materials and its software
and hardware revision numbers can be recorded. Most of this information is included in the factory
configuration; however, it can be edited as needed.
•
Ranges and limits
•
Common device information
•
Sensor information such as flange type, O-ring material, fill fluid, and diaphragm material
•
Remote seal specifics such as type and fill
•
Local meter selections such as type and local display units
•
Hardware and software revision numbers
Refer to the Online Configuration Map in Appendix A for details.
6.4.18 Flow Measurement (Differential Pressure)
The output current characteristic can be set to linear, proportional to differential pressure, or square root,
proportional to flow. There are two square root settings that affect the current output characteristic from
zero to the switch point (i.e. switch point). Figure 6-2 illustrates the three possible settings.
1. In the Online menu, press 3 Device Setup.
2. In the Device Setup menu, press 3 Basic Setup.
3. In the Basic Setup menu, press 7 Transfer Function.
4. In the Pressure Transfer Function menu, use an arrow key to cursor to the needed characteristic and
press ENTER to save the selection and return to the previous menu.
6.4.19 Diagnostic Functions
Communication with the HART Communicator enables activation and evaluation of numerous diagnostic
functions. The simulation of pressure and temperature measured values is possible, in addition to
calibration and service timers, min/max pointers, and limit value monitoring components.
A diagnostic warning or alarm can be configured to monitor limit values (e.g. monitoring of current
saturation).
Diagnostic Warning: The transmitter in which the diagnostic event has occurred notifies the HART
Communicator of the warning. The moving text "Diagnostic Warning" scrolls across the transmitter
display, alternating with the unit/bargraph display.
Diagnostic Alarm: The transmitter goes into a fault state. The message ERROR will appear and either
"Diagnostic Warning" or "Diagnostic Alarm" will scroll across the transmitter display, alternating with
the unit/bargraph display.
