Pulscon LTC
Function group "linearisation" (04)
semi-automatic
The tank is filled in stages when the linearisation curve is entered semi-automatically.
The Pulscon LTC 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, 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".
