OPERATION
Description
Tank type. Make a selection from the list of

select "Storage". If the surface of the product is

Tank height. The distance from the flange
face / thread stop of the tank connection
down to the tank bottom. If the tank has a
dish-shaped or conical bottom, the tank
height is measured to a point on the tank
bottom directly below the antenna.
Current output 1 variable. The manufacturer sets
the current output variable (for current output
1) to "Distance" before delivery.
If it is necessary to measure volume, ullage
volume, mass or ullage mass.
0% range. Use this step to give the 0% output
setting in the tank.
Refer to the illustrations that follow. When
menu item A4.1.3.1 Current Out. 1 Var. is set to
"Level", illustration 1 shows the position of 0%
output as a level above the tank bottom. When
menu item A4.1.3.1 Current Out. 1 Var. is set
to "Distance", illustration 2 shows the position
of 0% output as a distance below the flange
