SITRANS LU01 – INSTRUCTION MANUAL

7ML19985BE02

Use this feature if the surface is reported to be near the transducer face but is in fact 
much further away. Extend this value when changing transducer location, mounting, or 
aiming.

Please note that changing the Near Blanking cannot correct measurement problems. 
Ensure that Span (P007) < Empty (P006) minus Near Blanking (P800).

Used if incorrect level is reporated (when material level is lower than Empty, P006).

Range extension is the distance in Units (P005) or % of Span (P007) beyond Empty, which 
is still ultrasonically measureable. If empty is substantially higher than the actual vessel 
bottom, increase Range Extension such that Empty plus Range Extension is greater than 
the transducer to vessel bottom distance.

Used when the transducer is expected to be submerged on occasion.

When a transducer with a submergence shield is submerged, the shield traps an air 
pocket that creates a special echo. The SITRANS LU01 recognizes the echo and 
advances the reading to the highest level and operates displays and outputs accordingly. 
This feature is effective for when power is returned while the transducer is submerged.

Determines what type of ultrasonic shots are fired.
