distance too small
distance = ok
Use this function at part-covered probe. Choosing function "manual" or "probe free" at free probe.
• 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.
Note!
At free probe, the mapping should be confirmed with the choice "probe free".
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 "probe length." (031)
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 0.3 m (20") before the echo of the actual level. In case of empty
vessel it is possible to make a map over the whole probe length.
probe free
If the probe is uncovered, mapping is carried out along the whole probe length.
Caution!
Only begin mapping in this function if the probe is safely uncovered. Otherwise, the device will not
make correct measurements!
