APPENDIX B
SCREEN DESCRIPTION FOR BASIC SETUP MENU – 1/2
BASIC SETUP
Validate by pressing the * to enter the Basic Setup Menu.
CONFIGURATION
Validate by pressing the * to enter the Configuration sub-menu.
LEVEL
The instrument measures the level of a liquid in which the displacer is partially immersed.
INTERFACE
The instrument is used to measure the interface level between 2 non-miscible liquids of
different specific gravities. The displacer always must be immersed.
LEFT
Select the item in accordance with the relative mounting position of the instrument housing
versus the displacer. The standard mounting position is LEFT.
RIGHT
Optionally, the mounting position may be RIGHT.
DIRECT
An increase in level induces an increase of the loop current. Standard action is DIRECT.
REVERSE
Optionally, a REVERSE action can be selected. The loop current decreases when the level
increases.
SAVE
Validate by pressing the * to start the saving procedure of parameters previously entered in
the instrument memory.
CANCEL
Validate by pressing the * to cancel the parameters saving procedure.
COUPLING : %
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.

CALIBRATION of ZERO
and SPAN
Validate by pressing the * to get to sub-menu for Specific Gravity of Calibration setting, and
Zero and Span calibration.
SPECIFIC GRAVITY of
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.
LOW SPECIFIC GRAVITY
of CALIBRATION
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.
HIGH SPECIFIC GRAVITY
of CALIBRATION
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.
