5.2 Operation with the HART protocol.
The measuring device can be configured and measured values obtained by means of
the HART protocol. You have two options:
• Operation with the “HART Communicator DXR 275” universal handheld terminal.
• Operation by means of a personal computer using operating software (e.g. “Field-
Tool™”) and a HART modem (e.g. “Commubox FXA 191”).
5.2.1 HART Communicator DXR 275
Selecting device functions with a HART Communicator is a process involving a number
of menu levels and a special HART function matrix (see the “Description of Device Func-
tions” manual).
Note:
The HART manual in the carrying case of the HART DXR 275 handheld communicator
contains more detailed information on the device.
Procedure
1. Switching on the handheld communicator:
– Measuring device not yet connected
→ HART main menu appears → select
“Online” to continue
– Measuring device connected
→ “Online” menu level is displayed
2. “Online” menu level
– Display of current measured data such as flow, totalizer count, etc.
– Use “GROUP SELECTION” in the HART function matrix to select the function
group of your choice, for example “SYSTEM UNITS”, and then select the function,
for example “MASS”.
3. Enter a numerical value or make your selection from the options and press F4 =
Enter to confirm.
4. “SEND” appears above function key F2. All the values/settings entered with the
handheld communicator are uploaded to the measuring device when you press F2.
5. Press the HOME function key F3 to return to the “Online” level. You can now read
the current values that the measuring device measures with the new settings.
