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.
Function "range of mapping" (052)
This function displays the suggested range of mapping. The reference point is always
the reference point of the measurement (see page 57 ff.). This value can be edited by
the operator.
For manual mapping, the default value is 0,3 m.
Function "start mapping" (053)
This function is used to start the interference echo mapping up to the distance given in
"range of mapping" (052).
Selection:
• off:
no mapping is carried out
• on:
mapping is started
