P801 Range Extension
Allows the material level to fall below the Empty setting without reporting LOE.

This feature is useful in OCM applications where the Empty level is set to the bottom of
the weir, and above the bottom of the channel, and should be used if the surface
monitored can fall past the Empty (P006) level in normal operation. The value is added to
Empty (P006) and can be greater than the range of the transducer. If the surface
monitored can extend beyond Empty (P006), increase Range Extension (in Units (P005) or
% of Span) such that Empty plus Range Extension is greater than the transducer face to
furthest surface to be monitored distance. This is often the case with OCM when using
weirs and some flumes.
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 HydroRanger 200 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.
