2. If Full Point is less than the Minimum Range for the transducer, be aware that the UltraWave Series will not
detect or report material levels near the top of the Span. Full Point is normally 0.0.

Figure 13: Examples of Effect of Full Point, Span and Mode of Display
Example 1:
Span = 20’ (NOT interested in material level in cone)
Full Point = 0’ (Note that UltraWave Series will
not be able to detect material levels close to the
transducer)
Example 2:
Span = 30’ (Interested in material level in cone)
Full Point = 2’
