Function "check distance" (051)
This function triggers the mapping of interference echoes. To do so, the measured
distance must be compared with the actual distance to the product surface. The
following options are available for selection:
Selection:
• distance = ok
• dist. too small
• dist. too big
•
dist. unknown
• manual
distance = ok
• mapping is carried out up to the currently measured echo
• The range to be suppressed is suggested in the "
range of mapping (052)
" function
Anyway, it is wise to carry out a mapping even in this case.
dist. too small
• At the moment, an interference is being evaluated
• Therefore, a mapping is carried out including the presently measured echoes
• The range to be suppressed is suggested in the "
range of mapping (052)
" function
dist. too big
• This error cannot be remedied by interference echo mapping
• Check the application parameters
(002), (003), (004)
and "
empty calibr.
"
(005)
dist. unknown
If the actual distance is not known, no mapping can be carried out.
manual
A mapping is also possible by manual entry of the range to be suppressed. This entry is
made in the "
range of mapping (052)
" function.
Caution!
The range of mapping must end 0.5 m (20") before the echo of the actual level. For an
empty tank, do not enter E, but E – 0.5 m (20").
