Main menu
Setup - Medium
LEVEL TRANSMITTER 8138 • 4 ... 20 mA/HART - two-wire
The main menu is divided into five sections with the following func-
tions:
Setup: Settings, e.g., for measurement loop name, medium, applica-
tion, vessel, adjustment, signal output
Display: Settings, e.g., for language, measured value display, lighting
Diagnosis: Information, e.g. on instrument status, pointer, measure-
ment reliability, simulation, echo curve
Further settings: Instrument unit, false signal suppression, linearisa-
tion curve, reset, date/time, reset, copy function
Info: Instrument name, hardware and software version, date of manu-
facture, instrument features
Information:
In this operating instructions manual, the instrument-specific param-
eters in the menu sections "Setup", "Diagnosis" and "Additional set-
tings" are described. The general parameters in these menu section
are described in the operating instructions manual "Indicating and
adjustment module".
You can find in the operating instructions manual "Display and adjust-
ment module" also the description of the menu sections "Display" and
"Info".
In the main menu point "Setup", the individual submenu points
should be selected one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
Setup
Each medium has different reflection properties. With liquids, further
interfering factors are fluctuation product surface and foam genera-
tion. With bulk solids, these are dust generation, material cone and
additional echoes from the vessel wall.
To adapt the sensor to these different measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.
Through this selection, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with poor reflec-
tive properties, is considerably increased.
