P1-P106, P2-P1106 Span
This parameter should be set to the maximum distance from the Tank Depth
(P115/P1115) or Empty Level (P105/P1105) to the maximum material level. It is
automatically set to be equal to the Tank Depth (P115/P1115) or Empty Level
(P105/P1105) less the Near Blanking distance (P107/P1107), when you set the
tank depth or empty level.
When changing the Tank Depth (P115) or Empty Distance (P105) you can
also recalculate the values for the Span and the Relay Setpoints to take in to
account the near blanking (P107) and transducer depth (P116) where
applicable, so that they remain at the same percentage values of the empty
distance as they were before they were changed. The question “Recalculate
Span?” will be asked, if you choose yes (enter), then the span will be
recalculated, any other answer will leave the span at its original value. You
will then be asked if you want to “Recalculate Setpoints?”, if you choose
yes (enter), then all Relay Setpoints will be recalculated as a percentage of
the new empty distance, any other answer will leave the setpoints at their
original values.
