5. Set process empty level (P006: Empty)
Range
(depends on mode)l
Values
Default
Enter the distance from the transducer face to
process empty level (Empty) using units sets in
P005. Empty can be set to any distance: not
necessarily the bottom of the vessel.
Note:
P006 and P007 are interlinked: see
notes attached to P007.
6. Set the range to be measured
(P007: Span)
Range
Values (depends on model
Default
Enter the distance between Empty (process empty level) and Span (process full level), in
the units set in P005. Span can be set at any distance above the empty level.
Notes:
• Setting P006 resets Span, if it has not previously been set to a different value.
• The default setting for Span is based on Operation (P001) and Empty (P006). Span is
set to Empty minus 110% of blanking distance
(P001 = 3). In this case, Span is set to Empty distance.
• Always prevent the monitored surface from approaching within 0.3 m (1 ft) of the
transducer face. This provides a 0.05 m (2") safety margin, as the minimum detectable
distance is 0.25 m (10").
