ENGINEERING MENU
FOR THE 3102 AND 3105
Menu structures for this section are in Appendix C (Integrated Display Menus)
NOTE:
If using a HART Master Device for programming The 3102 or The 3105, refer
to the following sections for menu structures and parameters:
• Appendix D (Rosemount 3490 Series)
• Appendix E (HART Communicator).
• Appendix F (Parameters accessed over HART Communications)
Accessing the
Engineering Menu
(The 3102/3105)
Screen display: Eng
The transmitter can be fine-tuned if site or application conditions are unusual.
It is recommended that all operational fine tuning parameters remain at the
factory default settings unless there is a good understanding of the function
and capability of the parameters.
The “reload factory defaults” function is found in this menu, and should be
used if the transmitter has been configured incorrectly, or if the transmitter
needs to be reset to factory default values.
To reach the Engineering menu option “Eng”:
a) Begin from the PV display.
(Figure C-2 on page C-3 is a map of the menu structure.)
b) Press the blue button
→ to indicate the “DiAg” menu option. (To exit to the
PV display, press the red button
↵.)
c) Hold down the blue button
→ for 2 seconds, and then release. The display
changes to the “tEst” menu option. (To exit to the PV display, press
↵.)
d) Hold down both the blue button
→ and red button ↵ for 2 seconds. The
display changes to the “Eng” menu option. (To exit to the PV display,
press
↵.)
e) Press the green button
↓ to enter the “Eng” menu. The display indicates
the first engineering menu option “t.HoLd” (see below).
Setting the Threshold
(The 3102/3105)
Screen display: t.HoLd
Factory default value: Auto
False echoes are rejected below the threshold value. “Auto” sets the
threshold level for optimum performance based on echo sizes being received.
A value up to 99 may be entered. However, a large value will have the effect
of stopping false echo processing (see “Echo diagnostic” page 5-3).
NOTE:
This menu option is in the engineering menu “Eng”. See “Accessing the
Engineering Menu (The 3102/3105)” on page 5-6 or see Figure C-4 on
page C-5 for a map of the menu structure.
To change the threshold value:
a) After entering the “Eng” menu (see the note above), the first menu option
indicated is “t.HoLd”.
