Validate by pressing the * to enter the Basic Setup Menu.
Validate by pressing the * to enter the Configuration sub-menu.
The instrument measures the level of a liquid in which the displacer is partially immersed.
The instrument is used to measure the interface level between 2 non-miscible liquids of
different specific gravities. The displacer always must be immersed.
Select the item in accordance with the relative mounting position of the instrument housing
versus the displacer. The standard mounting position is LEFT.
Optionally, the mounting position may be RIGHT.
An increase in level induces an increase of the loop current. Standard action is DIRECT.
Optionally, a REVERSE action can be selected. The loop current decreases when the level
increases.
Validate by pressing the * to start the saving procedure of parameters previously entered in
the instrument memory.
Validate by pressing the * to cancel the parameters saving procedure.
Only necessary on instrument head delivered alone without torque tube. Function used to
mechanically couple the sensor to the torque tube rod. Requires simulating a displacer half
immersed in a liquid of S.G. 1.4. The value read must be between
-5% and + 5%. See Section 7.1.
Indicates the language in which the data are displayed on the screen.
Validate by pressing the * to get to sub-menu for Specific Gravity of Calibration setting, and
Zero and Span calibration.
Validate by pressing the * to set the specific gravity of the liquid used during the calibration
procedure. Settable value ranges from 0.001 to 10.
Used in case of an Interface instrument. Validate by pressing the * to set the Specific Gravity
of the lighter liquid used for calibration. Settable values range from 0.001 to the value of HSG
CAL.
Used in case of an Interface instrument. Validate by pressing the * to set the Specific Gravity
of the heavier liquid used for calibration. Settable values range from the value of LSG CAL to
10.0.
