Inferred Level
Out of Spec
The target has been lost within the
Max Distance Jump distance from the
Top or Bottom Blocking Distance
locations. As a result, the transmitter
has inferred that the level has moved
into one of those blocking regions, and
will report level measurement
corresponding to full or empty along
with the Inferred Level diagnostic
Verify level reading. If incorrect the
configuration may need to be adjusted.
