semi-automatic
The tank is filled in stages when the linearisation curve is entered semi-automatically.
The LUC-M** automatically detects the level and the corresponding volume/weight has
to be entered.
The procedure is similar to manual table entry, where the level value for each table point
is given automatically by the instrument.
!
Note!
If the tank is emptied (out litres), pay attention to the following points:
• The number of points must be known in advance.
• The first table number = (32 – number of points).
• Entries in "Tab. no." (043) are made in reverse order (last entry = 1).
table on
An entered linearisation table only becomes effective when activated.
clear table
Before making entries into the linearisation table, any existing tables must be deleted.
The linearisation mode automatically switches to linear.
!
Note!
A linearisation table can be deactivated by selecting "linear" or "horizontal cyl" (or the
"level/ullage" (040) function = "level DU" , "ullage DU" ). It is not deleted and can be
reactivated at any time by selecting "table on" .
