g) Repeat steps (e) and (f) until the last digit is flashing, and edited as
required.
h) Press the blue button
→ to confirm the new b.rEF value. None of the
digits should now be flashing.
i) If the new b.rEF value is correct, press the red button
↵ to save. The
display will change to the next menu option.
j) If the new value is incorrect, press the blue button
→ to exit to the menu.
The “b.rEF” re-appears; re-start at step (b) or press
↓ for the next menu.
NOTE:
• If the saved duty is Flow or Contents, the next menu option is “ProF”
(see “Selecting a Profile (The 3102/3105)“ on page 4-15).
• If the saved duty is Level or Distance, the next menu option is “4”
(see “Setting the 4 mA Point (The 3102/3105)“ on page 4-22).
NOTE:
A useful feature at this stage is that the transmitter can be used as an
electronic tape measure. With an empty tank or vessel, the transmitter will
read the distance to the bottom of the tank. This distance can be noted and
later used when setting b.rEF.
Selecting a Profile
(The 3102/3105)
Screen display: ProF
Factory default value: Lin
This menu is offered if the selected duty is Contents (Volume) or Flow, or is
shown when manually navigating the menu system - this section can be
ignored if the selected duty is Level or Distance.
The transmitter is pre-programmed with popular profiles that are
mathematical formulas to convert (scale) a linear level reading to a
flow or volumetric PV. Once converted (scaled), the 4–20 mA Output and
the Integral Display will operate according to the flow or volumetric PV.
The profile options are described in the following sections:
• “Contents (Volume) Measurement“ on page 4-15
• “Flow measurement“ on page 4-16
Contents (Volume) Measurement
Lin Linear (factory default setting)
H.CYL.F Horizontal cylinder on it' side with flat ends
SPH. Spherical vessel
H.CYL.D Horizontal cylinder on its side with dished ends
NOTE:
This menu option is in the programming menu. See Figure C-2 on page C-3
for a map of the menu structure and how to access the menu options.
To change the contents profile:
a) If entering the menu system from the PV display, press the green button
↓
repeatedly until the “ProF” menu option is indicated (see above note.)
