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).

P801 Range Extension

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.

P802 Transducer with Submergence Shield

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.

P803 Shot / Pulse Mode

Determines what type of ultrasonic shots are fired.
